Because people are so attached to their hair (pun intended), a number of myths have sprung up regarding hair — when and why it goes gray, what causes baldness, and how baldness can be prevented are just a few of topics of focus. Wherever people are going bald or worried about losing their hair, myths about hair abound. This page turns an objective eye to hair myths so you can separate the serious from the silly when it comes to hair loss.
1. Hair Loss Comes from Your Mother’s
You can get some insight into baldness by examining balding patterns in your relatives. If you have an uncle, father, or grandfather who’s bald or balding, find out when he started to lose his hair; it may be an indication as to when you may go bald. Just don’t put all the blame on Mom if you start to lose your hair. It’s not her fault!
Women also inherit the thinning or balding patterns found in their families, but the patterns that are inherited are distinctly women’s patterns, not men’s pattern. This suggests that the inheritance patterns in women do not follow the inheritance patterns in men. Women with hair loss or thinning will frequently report that they take after their mom, grandmother (either side of the family), sister, aunt, etc..
2. Wearing Hats Causes Hair Loss
WARNING: Hats that fit tightly on the head are another story. These hats may cause thinning around the sides of the head where constant traction is applied to the hair. Hats worn all the time for cultural and religious reasons (such as turbans and yarmulkes) may cause hair loss, too. In rare cases, sports helmets have been known to cause traction alopecia in athletes who wear their helmets too often, particularly if the helmet rubs repeatedly against an area of the scalp.
Risking it all to cover up
Many of my patients have lived underneath baseball caps for years, never venturing outside without them. The best example is my patient Sam, who was in the shower when the 1994 Northridge earthquake hit in California. Sam never went out without his baseball cap, but when his apartment started to shake and part of his building started to collapse, he put a towel around his waist and ran out of the apartment without his baseball hat on. When he reached the street half naked, Sam realized his head was also naked and immediately ran into the shaking, somewhat collapsing building to retrieve it. He returned to the street still wearing only his towel — but he had his baseball cap!
My office has many Open House events, and Sam comes to many of them to share this story with the audience of prospective hair transplant candidates and to show off his glorious hair. He never wears a baseball cap since finishing his transplant reconstruction.
3. If You Don’t See Hair in the Drain, You Aren’t Balding
Most people lose about 100 hairs daily but grow another 100 hairs daily to replace what’s lost. Some of the lost hairs wind up in your shower drain or hairbrush, or they may just fall off as you go about your normal activity, responding to whatever your environment dishes out.
Massive hair loss appearing in the shower drain should alarm you (as should a trail that forms behind you as you walk down the hall!), but insidious, progressive loss may be far more subtle. If progressive loss persists over time, you may lose far more hair than you’ll ever see in the shower drain. This is particularly the case with female hair loss.
4. Excessive Use of Hair Chemicals and Hot Irons Kills Your Hair
Damaging hair follicles below the skin, however, can cause baldness. When inexperienced people apply chemicals such as unsafe dyes or relaxing agents to the hair and scalp, the caustic chemicals may work their way into the growing part of the hair follicle and damage or kill the hair follicle at its root. The longer powerful chemicals stay on the scalp, the deeper they may penetrate into the pores of the skin where the hair follicles are, resulting in permanent hair loss or hair that may never look “healthy.”
Applying dyes, chemicals, or hot irons (even hair rollers that are too hot) can cause the hair to become fragile and break off as these hot irons may burn off the fatty layers in each hair shaft. Hair breakage and split ends are most common in people with long hair because the hair is around for a longer amount of time before being cut, so it’s more susceptible to damage from washing, wind, drying, and sunlight as well as chemicals such as relaxers and hair dyes.
5. Hair Loss Is Caused by Decreased Blood Flow
One hair loss myth says that standing on your head increases the flow of blood to your scalp and thereby improves hair regrowth and regeneration. Although the act may entertain the neighbors and give you a unique look on life (albeit an upside-down one), specialists agree that standing on your head has no impact whatsoever on hair loss. Growing hair does require a significant amount of blood flow, but after you lose hair, blood flow to your scalp decreases because, well, you just don’t need it with no hair up there.
There’s a cause and effect issue here, but it’s important to remember that the hair loss occurs before the blood flow decreases. Decreased blood flow to the scalp isn’t the cause of the hair loss but rather the result of it. The absolute proof of this is that, when good hair is placed into a bald scalp with decreased blood flow, the blood flow returns when the hair starts growing.
6. Magnets Increase Hair Growth
Over the years, I’ve been asked many times whether magnets can increase hair growth. The answer is a definitive “no.” Even if magnetic fields do affect blood flow — and that’s a dubious proposition — increasing blood flow to the scalp doesn’t prevent hair loss or regenerate hair.
7. Brushing Your Hair Is Better Than Combing It
TIP: You’re less likely to damage your hair using a wide-tooth plastic comb or brushes as opposed to a metal comb or one with finer, tighter teeth; these combs tend to be rougher and more traumatic to the hair shaft. When brushing or combing, direct your motion in the direction of hair growth so that the hair shaft (the grain of the hair) is in line with your brushstrokes.
8. Cutting or Shaving Your Hair Make It Grow Back Thicker
9. Hair Loss Is Caused by Clogged Pores
If common baldness were simply due to clogged pores, you wouldn’t need anything more than rigorous shampooing to maintain a full head of hair. But I’m sure you’ve seen men and women who don’t wash their hair often but who don’t seem to have a problem with balding. Men in particular buy into this clogged pore myth because they feel helpless at watching their hair fall out; when someone tells them that frequent massage and the use of special lotions will free up these clogged pores, they buy into it hook, line, and sinker. Of course, they do get some reward because the head massage feels great.
10. Frequent Shampooing Causes Hair to Fall Out
REMEMBER: Hereditary baldness isn’t caused by hair falling out but by normal hair which is gradually being replaced by finer, thinner hair and eventually just don’t get replaced when they are supposed to go through another hair cycle. Shampoo has nothing to do with baldness.
