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.
