The reason why hair falls off and withers is because hair follicles are unhealthy. Hair follicles will take many forms after they are unhealthy. The common one is hair loss, and the second one is dry and dull hair, which is also a manifestation of hair follicle damage. Because hair follicles can't provide enough nutrition for hair after being damaged, hair will fall off and dry without effective nutrition, so protecting the health of hair follicles is helpful to grow thick long hair.
Shaving can really stimulate hair follicles. When the hair follicle is always in a stable state, it may gradually close. At this time, shaving your hair and massaging your scalp often can stimulate hair follicles and accelerate hair growth. However, although this method has a certain effect, it can't help the subsequent growth of hair.
If it is because the hair follicle is damaged and appears unhealthy, it is necessary to restore the health of the hair follicle through relevant treatment in order to grow a black and beautiful hair. If you just shave your head, you can only stimulate hair follicles, but you can't achieve the really desired effect. In addition, in daily life, paying attention to the maintenance of hair follicles and hair is actually the best way to protect hair. Try to minimize perm and hair dyeing, because these will cause damage to hair follicles. In particular, some inferior hair dyes are very harmful to the scalp.
