If you pluck a strand of grey hair will two strands grow back? Here to bust common hair myths such as this is Trichologist Sally-Ann Tarver from The Cotswold Trichology Centre and Theradome GB.
We shed hair more twice a year in spring and autumn
Our hair is constantly shedding and re-growing, each hair follicle can do this around 25 times before it is exhausted. The spring shedding is the most common, this can usually be attributed to winter viruses such as the Flu. A virus around Christmas will often result in additional hair shedding in the spring. If your hair sheds in the autumn, look back 2-3 months at any stress or illness and you will probably find the answer.
If you pull out a grey hair two will grow back
Hair begins to grey when your natural colour pigment cells (melanocytes) basically run out. Once the process starts, unfortunately it’s a slippery slope and your grey hairs will increase whether you pull them out or not. Pulling out too many grey hairs too frequently will however lead to hair thinning!
Baldness comes from the mother’s side of the family
No actually, it is caused by a dominant gene, which can be inherited from both parents. Your mother can pass the gene onto you without appearing to have particularly thin hair herself. If your father went bald early, there is a pretty good chance your hair will thin too, but not necessarily as early as he did.
Heat protection spray stops straighteners damaging your hair
The only way to prevent heat damage caused my straightening irons is to either not use them, limit their use, use on the lowest heat setting and never ever use them on damp hair. Heat protection sprays may reduce burning of the cuticle (outer layer of the hair-shaft) but that’s about it. The heat damage from straightening irons is largely due to pockets of moisture trapped inside the hair-shaft which rapidly turn to steam under extreme heat. The steam can’t escape from the hair quickly enough and tiny holes are blown through the cuticle; a condition known as Bubble Hair Syndrome. Weak areas form and are exacerbated through continued heat abuse; leading to breakage and serious split ends. Unfortunately, coating your hair in silicone cannot prevent steam forming and escaping from the hairs structure.
