1. Minoxidil. It’s the only FDA-approved topical nonprescription medication that can claim to regrow hair — and it should be part of any hair-loss plan if you have serious thinning, says Rogers. Minoxidil has loads of research to back it, but it requires commitment. If you quit using it, your hair will start to lose ground again. Use a 5 percent strength, like Women’s Rogaine 5% Minoxidil Foam ($30), once daily to see results in three to four months, says Rogers.
Cicatricial or Scarring alopecia - hair loss occurs when inflammation damages and scars the hair follicle and replaces it with scar tissue. The inflammation that destroys the follicle is under the skin surface so affected areas of the scalp may show little signs of inflammation. It is not known what triggers or causes this inflammation. If the inflammation destroys the stem cells and sebaceous glands, then hair loss is permanent.
While diet alone won’t save your hair, there may be some truth to the old adage that you are what you eat. “You’re not going to have the healthiest hair if you’re living off doughnuts, because being nutrient-deficient weakens strands and makes them more prone to breakage,” says Denise Kernan, owner of DK Hair Techs, Inc., a member of the International Society for Hair Restoration Surgery, and a hair transplant technician who has worked on everyone from senators to sports stars to actors to mafia guys (she won’t name names to protect the privacy of her clients).
Losing your hair in the typical male pattern (where your hairline starts receding before getting thinner at the crown and the temples) is very common. When these two areas meet, it leaves hair at the sides and the back – in a horseshoe pattern. Eventually some men may go completely bald, while others might keep their hair around the back and sides (although some choose to shave these areas off anyway ).
Instead, you may want to add vitamin D (about $15) to your shopping cart. A vitamin D deficiency can exacerbate hair thinning and make it almost impossible for any over-the-counter product to reverse hair loss, says Dhaval Bhanusali, a dermatologist in New York City, who recommends taking 5,000 international units of D3 a day (and it’s generally beneficial for bone health in women over 40). “There’s also a link between low iron and zinc levels and temporary hair shedding, called [telogen] effluvium,” says Rogers.
However, researchers are still working to determine the best dose needed, whether the results are lasting, and whether they can develop a topical form of the drug, Day said. She added that patients should be aware that Tofacitinib has side effects. It's already associated with an increased risk of serious infections, as well as stomach and intestinal tears, according to Pfizer, the manufacturer.
