Ik kreeg vandaag een (Amerikaanse) nieuwsbrief waar o.a. het volgende in stond:
“Why do some people start seeing gray hairs in high school while others have a bright head of hair well into their golden years?The answer is a mix of genetics, age and overall health — with a few other factors thrown in.
Here’s what could be causing those silver strands to crop up…
1. Hydrogen peroxide buildup. H2O2 is produced naturally in your body, but you become less able to break it down as you age. As it builds up in your cells, it can interfere with melanin, the pigment that colors your hair.1
2. Vitamin B12 deficiency. Without enough B12, hair becomes dull, brittle and dry. You should know that some drugs may interfere with your absorption of the vitamin — for example, drugs used to treat acid reflux and ulcers, such as Pepcid, Prilosec and Zantac.
3. Smoking. The chemicals in cigarettes may damage the hair follicles and slow the production of melanin. Smokers are four times more likely to go gray prematurely.2
4. Stress. Although there’s no definitive proof that your kids or your demanding job cause gray hairs… stress may be a factor. Some researchers believe it affects your “follicle factories.””
Van punt 1. schrok ik nogal natuurlijk……..ik (en jullie) ne(e)m(en) juist éxtra H2O2! 😯
Het is niet waar zeker? 😕
