Unless you are balding, chances are good that you take hair for granted. A little shampoo and conditioner, a bit of styling product, and a good hair day is in your future—right? Not necessarily. Like all other body tissues, the state of your hair is related to your overall health and individual physical characteristics. Hair starts its lifespan in small, sack-like structures in the skin known as follicles. Each follicle produces a single hair shaft composed of a hard protein called keratin, which is arranged in long, tightly bound strands. New growth begins in the follicle and pushes outward so that the oldest part of the hair is furthest from the scalp. Each hair has a distinct growth cycle — active growth, maturation, and rest. During the resting phase, the follicle relaxes its hold on the shaft, so hair can easily fall or be pulled out. Every hair on your head goes through the growth cycle, but not at the same time. At any given moment, about 15 percent of all the hairs on your head are resting, and therefore capable of shedding . . . in your hairbrush, in the shower, on the bathroom floor. This is totally normal, and is not a harbinger of baldness. Between my two daughters and myself, our shower drain needs cleaning about every two weeks — that’s about all the “resting” hair it can take before it’s thoroughly clogged. Trust me, none of us is even close to bald. But if you have been experiencing unusual hair loss or problems with dryness, splitting, or breakage, or if you simply want to have more beautiful locks, nutrition can help. What Affects Hair Health? It is estimated that we each lose about 100 hairs a day. The actual number you’ll lose on any given day depends on how abundant and healthy your follicles are, what medications you’re taking, and many other factors, some of which are beyond your control. For example, the recommendations in this section won’t reverse thinning hair due to male pattern baldness or aging — typical male baldness is genetic. As we age, our hair spends more time in the resting phase, which means that we’ll shed more hair than usual, and it won’t grow back as quickly. For more general hair problems, here are some factors that you should be aware of: Hormonal Shifts Both male and female hormones affect hair growth. Male hormones known as androgens — a category that includes testosterone — stimulate hair growth on the face and body, and create fuller, thicker hair on the head. In women, ovaries and adrenal glands naturally produce androgens, but only very small amounts. If a woman suddenly starts growing facial hair, she should see her doctor — it could be a sign of a hormone-related health problem. For some men with a genetic susceptibility to baldness, normal testosterone is converted to a more potent form of testosterone (dihydrotestosterone, or DHT), which binds to cells in the follicle. DHT alters the growth/shed cycle and eventually kills the follicle. These men find themselves becoming bald in their 20s, a few years after their testosterone levels peak. Because the follicle itself shrinks and dies, this type of baldness is irreversible. Some prescription medications may short-circuit the balding process if caught early enough, though the medications need to be continued for life. In both men and women, levels of androgens decrease after about age 40, which leads to thinner, slower-growing, less luxurious hair as we get older. In contrast to androgens, the female hormone estrogen slows hair growth and creates a finer, thinner shaft of hair, which is why women are, on average, naturally less hairy than men. After menopause, levels of estrogen fall off dramatically, causing some genetically susceptible women to lose significant amounts of hair. Experts believe that female balding follows a processes much like male balding — without enough estrogen to off-set the tiny amounts of androgens in their bodies, they also can have androgen-related hair loss. But male and female hair loss aren’t identical. While men tend to bald in a distinct pattern that includes a receding hairline and hair loss at the crown, women tend to lose hair evenly, leaving them with a sparse head of hair instead of a totally bald scalp. When levels of estrogen and progesterone are both high, such as during pregnancy, the combination works to synchronize the hair growth cycles, so more hair is in the growth stage at the same time. In the second and third trimester of pregnancy, the percent of hair in the resting phase falls by one-third to about 10 percent. For those few months, pregnant women have the fullest, richest heads of hair they’ll have in their entire lives. About three months after delivery, the percent of shedding hairs goes back up to 15 percent. As all those synchronized hairs enter the resting phase together, it can look like you’re suddenly losing all your hair. Don’t panic! Once the hair starts to regrow, it returns to its usual growth/rest cycle. Stress
Stress is one of the most common causes of unusual hair loss. Accidents, major illnesses, severe psychological stress, or other traumatic events can send hair follicles into the resting phase prematurely. Around three months later, when those resting follicles release the hair shaft, large amounts of hair can seem to fall out simultaneously, and for no discernable reason since several months will have passed since the event that triggered this whole episode. Again, getting through this is simply a matter of waiting it out. Your hair should begin to regrow almost immediately. Lack of Protein Hair is made of protein. All basic nutrients contribute to keeping us whole and healthy, but protein provides the building blocks that allow us to repair, replace, or grow bones, skin, muscles, and hair. Although we tend to think of dietary protein as coming from steak, fish, chicken, and other meats, it is also found in eggs, legumes (such as starchy beans and lentils), dairy products, soy foods, and — in smaller amounts — some whole grains and vegetables. People who don’t get enough protein in their diets, such as those with anorexia nervosa or who follow any extreme weight-loss diet, will slow the rate of new hair growth. As hair is naturally shed, it won’t grow back as quickly. With enough hair loss, the scalp will start to show through. Starvation also depletes the body of other nutrients important for hair growth and quality. And over the long term, starvation and extreme weight loss will lead to a reduction in hormone production, which can also lead to thinning hair. Medications and Supplements Most people understand that chemotherapy treatments for cancer can cause widespread balding, but many other commonly prescribed medications may lead to less extensive hair loss. These include anticoagulants (such as warfarin), antidepressants, oral contraceptives, and medications for blood pressure, gout, or arthritis. In addition, very high doses of vitamin A and selenium are toxic and can cause hair loss. This type of toxicity happens only if you take high-dose supplements, so don’t take individual supplements for vitamin A or selenium. If you take a multivitamin supplement, it shouldn’t contain more than 100% DV for vitamin A (5,000 IU) or selenium (70 micrograms). Better yet, make sure your multivitamin provides 50 to 100% of its vitamin A in the precursor form of beta carotene and/or mixed carotenoids. There is no known chance of Vitamin A toxicity when you’re getting your standard supplemental dose from carotenoids. Because beta carotene in food and supplements is converted to the active form of vitamin A by your body in controlled amounts, you won’t make more than your body needs. Once you stop taking the medication or supplements, hair will usually begin to grow back within a few months. Thyroid Gland Malfunction and Other Disorders Thyroid hormones affect the metabolism of all cells, including cells in hair follicles. Too much thyroid hormone (hyperthyroid) or too little thyroid hormone (hypothyroid) can result in thin, brittle hair or hair loss. With uncontrolled diabetes, body cells (including cells in hair follicles) starve because glucose can’t get in; and in systemic lupus erythematosus, the body attacks its own collagen, including the collagen in hair follicles. These disorders and many others — including celiac disease, rheumatoid arthritis, ulcerative colitis, and Crohn’s disease — may cause hair loss or damage by altering cell metabolism or structure. Once the underlying disease is treated, hair growth should return to normal. All cases of unexplained hair loss should be investigated by a physician to rule out the possibility of serious disease. Reference: joybauer.com Your diet is hugely important to the health of your hair, and the effects of your daily nutrition on its growth and appearance should not be underestimated. To help you understand this better, we will put hair growth and the energy needed to sustain it into perspective.
Your hair is comprised of the second fastest-growing cells in your body – intestinal cells being the first. To add to this, you have roughly 120,000 hairs growing on your scalp at any given time, all of which need to be supported. However, what may be the most challenging part of sustaining hair growth is this: hair is not a vital organ or tissue, and this means your body will never prioritize its nutritional needs. Due to its expendable nature, a nutritional imbalance will often show up first in the form of excessive hair loss. Hair and scalp problems can arise from either a deficiency or an excess of nutrients in your diet, and in some cases nutrition alone can be the cause of hair loss. For example, in both our London and New York Clinics, we often see hair loss as the sole result of iron and ferritin (stored) iron deficiency. We have also seen hair loss from too much Vitamin A. However, what many people have been led to believe is a ‘healthy diet’ often doesn’t include all of the elements needed for optimum hair growth, health and appearance. These include diets that consist of mainly of fruits, vegetables and salads, with only minimal amounts of protein and calories. Or, on the other end of the spectrum, diets that are high in protein and fat, with little or no carbohydrates (i.e. an Atkins-type diet). Your hair cells, as well as the cells throughout your body, need a balance of proteins, complex carbohydrates, iron, vitamins and minerals to function at their best. For breakfast and lunch, we suggest including a portion of any primary protein (i.e. fish, chicken, lean meat, or 2 eggs) with a portion of complex carbohdrates. For example, whole wheat toast, potatoes (with skin), oats, barley, brown rice, or pasta. Reference: philipkingsley.co.uk 1. Remember that it can't grow overnight. Unless your scalp unleashes new strands like a Chia Pet, gaining new length is going to take time. "Hair typically only grows about a quarter of an inch — to a half an inch max — a month," says celebrity hair stylist Mark Townsend, who helped Ashley Olsen grow out her asymmetric bob to past her waist. "And that's only if it is super-healthy and doesn't have a ton of split ends." The bottom line: Practice patience. 2. Ironically, scissors are your friend. Although getting regular trims to snip splits won't make your hair actually grow faster, it will keep tips looking healthy and prevent splits from working their way up strands, requiring you to chop hair off more often. "If you wait so long that splits are causing your hair to break off high up on the strand, your hair will actually be shorter than if you get consistent trims," Townsend says, who suggests asking your stylist to take around just an eighth of an inch off every 10 to 12 weeks to prevent extreme split ends before they start. 3. Use conditioner every time you shampoo. "If your hair is wet, that means you have to condition it," Townsend says. "Over time, from coloring and heat styling, strands start to get thinner at the bottom." Conditioner helps replace the lipids and proteins inside the hair shaft, "as well as seal the cuticle to help prevent more damage from happening so that you can get your hair to grow longer and look healthier," he says. 4. And don't shampoo every time you shower. "It's shocking to me how many women skip conditioner when showering, which is the worst thing you can do for your hair — especially when you're trying to grow it long — and it's actually shampoo that you should be skipping as much as possible," Townsend says. Here's why: The purpose of shampoo is to wash away dirt and product buildup, but it can also take essential natural oils that keep strands soft and healthy along with it. When you really do need shampoo, be gentler on your hair by only lathering up at your scalp and then simply letting the suds slide down strands, hitting the rest of the hair as the water rinses it away. 5. Do a cold-water rinse at the end of each shower. "This really does help to grow hair and keep long hair healthy for longer," Townsend says. "Cold water lays down the outer layer of hair more smoothly, which helps prevent moisture loss, snags and heat damage — you only need to do it for a few seconds, but this one extra step over time can make a huge difference." 6. Apply an oil or mask treatment weekly. Hair that touches your shoulders or beyond can be several years old and most likely needs more TLC than normal conditioner. Townsend suggests using moisture-based masks and oils weekly. "I make a natural oil treatment and give it to all of my clients to use pre-shampoo," Townsend says. (His easy recipe: 1 cup of unrefined coconut oil mixed with 1 tablespoon each of almond, macadamia, and jojoba oils.) Because oils can leave a residue on hair, he says to apply it to damp hair, leave it on for 10 minutes, then shampoo and condition like normal. "These oils are able to fill strands up with fatty acids and then, when rinsed out, using regular shampoo helps seal them inside hair," Townsend says, adding that Kate Bosworth, Diane Kruger, and Ashley and Mary Kate Olsen are fans. Not into DIY? Try an oil-based hair treatment instead. 7. Consider trying hair-boosting supplements. Your body requires many vital nutrients to create new hair, from ample protein to a slew of essential minerals. So take a look at your diet — because while eating a balanced diet helps, you may not be getting the proper amount of all the hair-building nutrients needed to create healthy hair that can grow super-long and withstand damage. "I take Viviscal Extra Strength and biotin tablets every day and tell my clients to do so as well — especially if they want to grow their hair and make it healthier as soon as it comes out of the follicle," Townsend says. Before starting to take supplements, it's best to check in with your doctor to make sure that you take the right amounts and that they won't interact with any medications you're currently taking.
8. Brush your hair like it's spun from gold. Constant brushing can cause physical harm to your hair. "When you detangle wet hair, be sure to start from the bottom and work your way up — we often instinctually go from the scalp down, but that just brings small tangles into one large knot and can cause you to lose a lot of hair," Townsend explains. He also suggests reaching for the Sheila Stotts Natural Boar Bristle Brush, as boar bristle brushes are good at distributing your scalp's natural oils down your hair and being extra-gentle on strands too. 9. Ditch your cotton pillowcase. Townsend recommends switching to a silk or satinfabric, because it has a softer surface that won't cause friction the way that regularly woven cotton does with your hair. That way, you'll wake up with fewer tangles. 10. Never, ever wrap your hair in a massive towel again. What could be so bad about putting hair in your super-soft bath towel? A lot. "It causes so much breakage," Townsend says. "Your hair gets caught in all the woven fibers and since most women almost always wrap it too tight around their face, all those tiny, fragile strands around your face are more prone to break." Opt for the super-thin and soft microfiber hair towels instead (like Aquis microfiber hair towel), which are totally OK to wrap into a turban. 11. Switch up your pony placement. It's an easy move that can help maintain the integrity of your strands wherever you tend to secure your ponytail all the time, which means they'll continue to grow out strong and damage-free. 12. If you have bleached (or dry, super-fragile) hair, skip putting it up with a hair tie at all. One ponytail — one! — can give you what stylists refer to as a "chemical cut." This is where your hair literally breaks off at the point of tension where the elastic ends up being wrapped around your hair to hold it into place. Instead, if you're looking to work out and want your hair off your neck, gently twist your hair into a bun and clip it with a tiny claw clip, bobby pin, or larger pin. 13. Give your hair a break when it comes to hot tools, chemical relaxers, or any other tool or service that causes a lot of damage to your hair. The healthier your hair is, the longer it will grow. |
