Why Dandruff Shampoo Can Prevent Thinning Hair



At any one time,​ about 10 percent of​ the​ hair on​ your scalp is​ in​ a​ resting phase. After 2 to​ 3 months,​ the​ resting hair falls out and new hair starts to​ grow in​ its place. This growing phase lasts for​ 2 to​ 6 years. Each hair grows approximately 1 centimeter per month during this phase. About 90 percent of​ the​ hair on​ your scalp is​ growing at​ any one time.

Hair loss is​ a​ common problem among men and women. About 25 percent of​ men begin balding by age 30 and two-thirds begin losing hair by age 60,​ according to​ the​ American Medical Association.

A number of​ things can cause excessive hair loss. for​ example,​ about 3 or​ 4 months after an​ illness or​ a​ major surgery,​ you​ may suddenly lose a​ large amount of​ hair. This hair loss is​ related to​ the​ stress of​ the​ illness and is​ temporary.
Hormonal problems may cause hair loss. if​ your thyroid gland is​ overactive or​ underactive,​ your hair may fall out. This hair loss usually can be helped by treatment of​ the​ thyroid disease. Hair loss may occur if​ male or​ female hormones,​ known as​ androgens and estrogens,​ are out of​ balance. Correcting the​ hormone imbalance may stop your hair loss.

Dandruff is​ one of​ the​ causes of​ Hair loss. Dandruff is​ caused by a​ fungus known as​ malazzesia globosa. This fungus is​ commonly found floating in​ the​ air which is​ why dandruff can be treated,​ but not cured. Studies have shown that with only 90 minutes of​ continuous scratching by the​ fingernails,​ it​ is​ possible to​ remove all of​ the​ cuticular scale,​ a​ protective covering on​ individual hairs,​ off of​ a​ hair shaft. This loss leaves the​ hair shaft weakened and permanently damaged,​ making it​ easily susceptible to​ breakage and hair loss.

“The most effective dandruff shampoos and conditioners contain zinc pyrithione,​” advised Dr. Draelos. “These ingredients leave behind thin plate-like pieces of​ medicine on​ the​ scalp to​ prevent regrowth of​ the​ fungus,​ thus acting as​ a​ preventive measure for​ both dandruff and the​ hair loss associated with scratching.”
Therefore,​ don’t just ignore the​ itch,​ invest in​ proper treatment.
