Devices that emit low-energy laser light may help new hair grow. They're available in some clinics and for home use. Several are approved for both men and women, and studies show they do work. But it might take 2-4 months before you see results. Keep in mind: The FDA doesn’t require the same rigorous testing for devices as for medicines. The long-term safety and effects aren’t known.
It’s good to know that hair loss is a hereditary thing. My husband’s father has hair that is thinning out quickly, so I imagine that my husband will have a similar problem in the future. If that’s the case, then I should probably look into some preventative treatments to help him out. After all, the last thing I want is for my husband to start balding at age 40!
