Hair loss comes from the mother’s side
False. While baldness is genetic, it is not limited to the maternal side of the family. The hair-loss gene can come from either side. If your uncle Charlie on your father’s side has a receding hairline, then chances are you might not be in the clear. Brushing the hair 100 times a day will stimulate the circulation and prevent hair loss False. Vigorous brushing is more likely to injure the hairs and make the problem worse.
Hair needs to breathe, so wigs and toupees worsen loss of hair
False. Hair does not need to breathe. Only the root of the hair is alive and this gets its oxygen from the blood in the scalp. Wigs and hairpieces will damage hair only if they are too tight.
Frequent shampooing makes hair fall out
False. Shampooing simply gets rid of the hairs that have already fallen out.
Wearing hats causes hair loss
False. In order for the hair to fall out, the hat would have to be so tight that it cuts circulation to the follicles. So no, wearing hats does not cause hair loss. Could you just imagine how many pro sports players would be bald if that were the case?
Blow-drying and heated brushes can worsen hair loss
True. The reason is that extreme heat damages the proteins in the hairs, making them fragile and liable to break off. Brushing the hair during blow-drying causes more damage. Careless use of heated brushes can even burn the scalp, so that the hair follicles are permanently damaged in that area.
Hair dyes, perms and hairsprays worsen hair loss
False. Hair dyes, perms and hairsprays do not affect thinning hair. Perms and hairsprays can help to disguise the problem.
If your father has a full head of hair, you will not go bald
False. A tendency to baldness is inherited and probably involves a combination of genes. So you are not automatically in the clear even if your father has a full head of hair. It is not true, as sometimes claimed, that only genes from the mother’s side are involved.
Stress can cause hair loss
True. Scientists have now identified some chemicals that are produced in the body during periods of stress, which can affect hair growth (Journal of Investigative Dermatology 2004;123:455–7).
It is normal to lose hair from our early 30s
True. A person aged 20–30 years typically has 615 hair follicles per square centimetre. The number falls to 485 by 50 years of age and to 435 at 80–90 years of age. Also each hair is thinner. So, with ageing, hair becomes both finer and sparser.
Cutting your hair will make it grow back thicker
False. This common misconception comes from the fact that hair is thicker at the base than it is at the tip, so it appears thicker at first. Cutting your hair does not affect hair growth at all; it will grow about half an inch each month no matter what.
