There are a variety of methods available for the regrowth of hair follicles, from using medication to massaging your scalp to stimulate your hair directly. Currently, the most effective way to reactivate your hair follicles is by using medication, such as finasteride and minoxidil.
If you damage your hair follicles after an injury, they can repair themselves and your hair will grow back. It could take up to four years before you see new hair growth out of damaged hair follicles, depending on the severity of your injury.
But even though some of your hair follicles may eventually go dormant and stop producing new hairs altogether, these sleeping follicles are not a lost cause. Regular scalp massages and topical hair products with the right stimulating ingredients can effectively wake them up and trigger hair production again.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr.

One very good medication to reactivate dormant hair follicles is minoxidil. Applied regularly to the scalp, minoxidil can re-grow hair that has completely stopped growing. The only caveat is that once you start taking it, you'll have to keep taking it indefinitely.
Hair follicles typically grow back within one to two months as long as your scalp does not need to recover from damage. If your hair follicles are damaged, it can take up to four years until they are able to regrow hair normally unless it is permanent, in which case no new strands will grow.
When hair follicles die, however, hair growth stops completely. To know if your hair follicles are still active, just take a look at the scalp on your head. If you see any hairs on your scalp—no matter how sparse, thin, short or fuzzy—your hair follicles are still alive and kicking and sprouting new hairs.
Electrolysis. This method sends an electrical current through a hair follicle, which will damage the follicle and prevent hair from growing. Because hair grows in cycles, it takes several sessions to get permanent hair removal. You'll also find kits that allow you to perform electrolysis at home.
Using oils such as black seed or hibiscus are known to stimulate hair follicles and encourage regrowth. Another oil known for its ability to strengthen hair follicles is marula oil which coats hair strands and penetrates the scalp. The application of an onion juice treatment weekly will also help with this.
New research has allowed scientists to generate new hair follicles — those tube-shaped pores that hug the strand and root of a hair — in vitro in a lab. It's a development that experts say can open pathways for better hair loss treatments in the future.
"ACV unblocks follicles in the scalp so that strands have freedom to thrive," Ruggeri says. (Note: If you do use dry shampoo, Ruggeri advises spraying it on the mid-lengths of hair, rather than the roots, to prevent clogging the follicle).
Iron deficiency (ID) is the world's most common nutritional deficiency and is a well-known cause of hair loss.
Vitamins B and D factor big in healthy hair. So do zinc, omega-3 fatty acids, and the B vitamin biotin. Your doctor can test you for deficiencies. Ask them whether you should take a multivitamin or supplement and how much.
Dormant hair follicles can occur from physical damage to the hair follicle, leading to it no longer being able to grow hair. Or, more commonly, hair follicles can be slowly miniaturized from exposure to a hormone called DHT (dihydrotestosterone).
Then is the telogen or resting phase. The follicle becomes dormant for around 1 to 4 months. The club hair that has been formed keeps the hair in the follicle for several months, but the hair is no longer in anyway alive or growing.
But once a hair has fallen, regrowth may not continuously occur, as the follicle becomes inactive. The bulb is not dead but asleep, said Dr Bernard, and this dormant phase can last from two to 12 months before it wakes up to give a new hair.
“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.
