A: False. Shampooing does not generally cause hair loss; it just removes the hairs that were about to fall out anyways. Coloring, perm, and conditioning doesn’t typically cause hair loss either. Burns or severe processing may lead to hair loss as well as breakage. Styles that pull tight may result in some losing but color treatments usually don’t.

A: Three years. In this case, normal means hair lives for about three years until it enters a resting phase called telogen.

A: Alopecia areata. Alopecia areata is an self immune disorder where the body produces antibodies that attack individual hair follicles. This usually appears first as one thin patch of baldness about one inch wide and 1mm thick. These patches will often disappear in 3-6 months without treatment but if they continue to reappear then they could become chronic – permanently disappearing and being replaced by new thinner hair growths until eventually, only fine vellus hairs remain (peach fuzz). People who experience this problem typically do not lose all their hair on top of their head when they just have localized thinning/balding.

A: There are three main stages; anagen, catagen, and telogen. The initial stage is the anagen phase where hair begins to grow at rapid rates. The next stage is the catagen phase where some of your strands become thinner until they eventually stop coming out at all. The final stage in the natural process of human hair growth is termed as telogen; this phase entails it being ready for shedding and new strands beginning their cycle from the end or base upwards.

A: Thyroid. About half of all people with hair loss have some type of thyroid problem, either hypothyroidism (underactive) or hyperthyroidism (overactive). Hair loss can be a consequence of other ailments such as low iron levels and anemia. However, those cases are less common than the thyroid problems that take part in around half of all cases.
