Consuming omega fatty acids can help to improve your hair from the inside, since they are filled with nutrients and proteins. Taking an omega supplement along with antioxidants helps to improve hair density and diameter. It also reduces hair loss. Omega fatty acids help your cells to work correctly and can boost immunity, leading to better overall health. Follow the manufacturer’s recommended dosage.
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.

The only nonchemical option offered up by the dermatologists I spoke with — short of a surgical hair transplant or platelet-rich plasma therapy, which is like Kim Kardashian’s vampire facial but for your scalp — was the laser comb. First cleared by the FDA in 2009, the HairMax LaserComb is a handheld laser device that is designed to promote hair growth. As the manufacturer explains in a letter to the FDA, “The device provides distributed laser light to the scalp while the comb teeth simultaneously part the user’s hair to ensure the laser light reaches the user’s scalp,” which, in turn, stimulates the hair follicles.


The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.
