"As we age, hormone levels change (consider menopause in women), and hair follicle size also diminishes, contributing to hair loss," she says. "In men, hair loss due to aging frequently begins at the temple and crown; in women, it is more widespread across the scalp, but not as noticeable."
“Vitamins are essential for healthy hair growth and may help in preventing hair shedding and thinning,” says Michele Green, M.D., a cosmetic dermatologist in New York. “The best vitamins for hair growth include B vitamins, vitamin D, vitamin E, zinc, biotin and iron.
Because of these aging and environmental changes, some hair follicles stop producing new hair altogether. Over time, hair fibers become thinner and drop out, and unfortunately, they never regenerate.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
To promote hair growth, you need to increase your protein intake, especially by consuming food like fish, beans, nuts, and whole grains. Hair follicles are mostly made of protein, and the lack of it promotes hair loss. Proteins 'feed' the hair from the inside.
Seeing a visible scalp is often a sign of fine hair, and genetics can be the primary cause for this type of hair loss. However, other common causes of thinning hair include stress, hormone imbalances, certain medications, illness or infections and malnutrition.

Treatments such as Vaporub might be able to alter the appearance of the hair you already have or make the hair appear thicker and help with issues such as dandruff. However, there is no scientific evidence of it stimulating the hair follicles and resulting in new hair growth.
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
Hormonal changes and medical conditions.
A variety of conditions can cause permanent or temporary hair loss, including hormonal changes due to pregnancy, childbirth, menopause and thyroid problems.
You may have female pattern hair loss (FPHL), a condition that affects millions of women. FPHL is actually the most-common cause of hair loss in women. For most women, FPHL begins in midlife, when a woman is in her 40s, 50s, or 60s. It can begin earlier for some women.
