Many other women, though, start noticing thinning hair on top of their heads. Doctors say the defining sign is a widening of the part. The hairline itself is usually intact, but the hair becomes less dense behind it. Doctors will often run a battery of tests to make sure there are no treatable medical conditions, such as anemia, thyroid problems, tumors, or hormonal problems. "Ninety percent of the time, it's normal," Patel said.
Hair is made up of the hair follicle (a pocket in the skin that anchors each hair) and the shaft (the visible fiber above the scalp). In the hair bulb, located at the base of the follicle, cells divide and grow to produce the hair shaft, which is made from a protein called keratin. Papilla that surround the bulb contain tiny blood vessels that nourish the hair follicles and deliver hormones to regulate the growth and structure of the hair.

More good research coming from the University of Alabama at Birmingham shows that a certain gene affecting mitochondrial function can dramatically reverse signs of aging in mice. The aging factors which were shown to be reversible include skin wrinkles, gray hair, and hair loss. Next comes the important phase where the researchers continue forward to translate this discovery to human use. Full article on the front page.

Late last week, HairClone officially unveiled its crowdfunding campaign with the Euro-based crowdfunding company Capital Cell.

Your hair can suffer from many health-related factors. A diet that is lacking in vitamins and minerals lack proper hydration as well as damage from styling. Make sure you eat a varied and balanced diet with plenty of nutrient-rich foods including fruit and vegetables. Try and limit using heat to style. This includes hairdryers and straightening irons.
Not surprisingly, treatments with 5 percent minoxidil work better than treatments with 2 percent minoxidil. A randomized clinical trial published in the American Journal of Clinical Dermatology in 2002 found that, in men with androgenetic alopecia, “5 percent topical minoxidil was clearly superior to 2 percent topical minoxidil and placebo in increasing hair growth.” The difference was actually pretty astounding — after 48 weeks, the men who used 5 percent minoxidil experienced 45 percent more hair growth than the men who used the 2 percent treatment.

Dupilumab is FDA approved for treating eczema aka atopic dermatitis and sold under the brand name Dupixent.  As the story goes, a patient with alopecia totalis (a form of areata which leaves a person’s head completely bald) was being treated for eczema by the drug Dupixent. After 6 weeks the patient first began to notice progress in terms of hair growth and at 7 months she had noticeable pigmented hair growth on her scalp. Notably, the patient stopped taking the dupilumab for a period of time and noticed her growth subsided; when she began taking the drug again the hair improved once more. This provides another useful therapy option for patients seeking treatment for AA. One would imagine a topical version would be worthwhile to investigate.
