6 surprising hair myths and facts
Here's what you need to know about the varied growth atop your head.
1. Brush 100 times a day for healthier hair. Myth.
This is now known to risk damaging your mane. Brushing pulls out hair that isn’t ready to fall out, often breaks healthy hairs, and scratches the scalp. Brush gently for styling only, not to stimulate the scalp.
2. Being stressed can make your hair fall out. Fact.
Severe stress can take a toll on your hair. All hair follicles normally undergo periodic “rest” periods; sudden stress can cause them to enter this resting phase prematurely, making the hair fall out in the three months following the stressful event. Normally hair growth restores naturally, but it’s important to deal with stress and seek medical advice to rule out underlying illness, hormonal imbalance, or medication side effects.
3. Worry brings grey hair. Fact.
The stress hormone adrenaline may damage DNA in the genes responsible for the production of melanin, the pigment that gives hair its colour. 4. Hair can turn white with fright. Myth. You can’t lose pigment in your hair because hair is dead when it leaves the scalp. But a severe shock could trigger alopecia areata, an autoimmune condition that causes hair to drop out. In rare cases this can attack only pigmented hairs, leaving gray and white hair behind.
4. Hair grows faster in the summer. Fact.
When it’s cold, blood is diverted to internal organs to maintain body temperature, which decreases blood flow to the scalp. In warm weather, enhanced circulation to the skin boosts follicle activity and increases the rate of hair growth. Hair grows 10-15% faster in summer.
5. Cutting hair by the moon speeds its growth. Myth.
Some people believe that cutting hair under a waxing moon promotes growth. Alas, hair does not grow back more strongly after it’s cut – at any time.
