It depends. “If a follicle has closed, disappeared, scarred, or not generated a new hair in years, then a new hair wouldn't be able to grow,” Fusco says. But if the follicle is still intact, yes, it is possible to regrow the hair—or to improve the health of the existing thinner hairs.
You might be able to reverse hair loss, or at least slow it. With some conditions, such as patchy hair loss (alopecia areata), hair may regrow without treatment within a year. Treatments for hair loss include medications and surgery.
However it is possible to revive dead hair follicles in certain cases if the follicles are at the initial stage of damage, and the growth phase can return. If the hair follicles have been dormant for a long time there's only a rare chance that they'll grow back.
Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.

Minoxidil
Best known as its brand-name Rogaine, minoxidil is an over-the-counter hair loss treatment approved by the FDA. When applied directly to the scalp twice a day, minoxidil may gradually thicken hair in balding spots. The product is available in either liquid or foam, depending on your preference.
After about a month, hair may begin to grow back at its typical rate of 4 to 6 in. per year. Keep in mind that, in some cases, it can take up to a year for hair to start growing following chemotherapy. Your new hair may grow back a different texture or color than before.
Here's the truth: You can't change the size of your hair follicles. If you were born with fine hair, it's genetics, and no product will completely alter that. Of course, there are ways to maintain your hair health, add volume, and keep it from getting any thinner.
Genetics, hormones, nutrition, and stress levels all play a role when it comes to the health and growth of tresses. An average person loses about 50 to 100 hairs every day and grows the same amount.
Iron deficiency (ID) is the world's most common nutritional deficiency and is a well-known cause of hair loss.
A small study showed that applying onion juice to the scalp twice a day might help hair regrow in some people. Almost 74% of participants had some hair regrowth after 4 weeks, and at 6 weeks about 87% experienced hair regrowth.
