For most people, the most obvious sign of hair follicle damage is hair loss. As your follicles become damaged, they may stop growing new hairs, resulting in a receding hairline, bald spot at your crown (the area at the top of your head) or diffuse thinning.
Unfortunately, once your hair follicles have been deeply damaged, it is permanent. Your best bet is to spend your time, energy, and resources focusing on protecting and caring for the healthy follicles. You can also take steps to support new hair growth.
Do hair follicles heal after an injury and will my hair grow back? 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.
Symptoms such as itching or pain in the scalp associated with hair loss may indicate scarring alopecia. A physical exam of the scalp coupled with a scalp biopsy will confirm a diagnosis.
Causes of Cicatricial Alopecia
Generally, cicatricial alopecia is caused by inflammation, which damages the hair follicle. Damage can also stem from a trauma such as a burn or serious infection. The inflammation can involve different types of cells, including lymphocytes, natural killer cells, or several cell types.
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.
Treatment Options
Scarring alopecias that involve mostly lymphocyte inflammation of hair follicles, such as lichen planopilaris and pseudopelade, are generally treated with corticosteroids in topical creams and by injection into the affected skin. In addition, antimalarial and isotretinoin drugs may be used.
Hair doesn't naturally grow in scar tissue because there aren't any hair follicles in a scar. Hair follicles are capsules underneath the skin that hold and regrow hair. Blood vessels under follicles help them grow and regenerate. But when a scar forms on damaged skin, hair follicles don't grow back.
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.
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.
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.
Unhealthy hair usually has a rough texture, lack of shininess and luster, have split ends, lack of moisture and elasticity even after treatment and easily broken. Damaged hair will also get tangled up and result in knots due to hair dryness.

It is recognized that for men it usually lasts 2-4 years, while for women 3-6 years. The catagen phase represents the moment in which the follicle starts to diminish and slowly ceases mitosis. It has a duration of around 7-21 days. It is difficult to find hair in a trichogram during the catagen phase.
Mild folliculitis will likely heal without scarring in a few days with basic self-care. More-serious or repeat infections may need prescription medicine. Left untreated, severe infections can cause permanent hair loss and scarring.

Terminal hair is the thick, coarse hair that grows on your scalp and makes up your eyelashes and eyebrows. After puberty, terminal hair may also grow on your face, armpits, pubic area, chest and belly (abdomen). Terminal hair covers about 30% of your body's surface in people assigned female at birth.

Blocked hair follicles range in severity from mild to severe. They start out looking like small and irritated red pimples. Over time, they may look like pus-filled lumps, cysts, or boils. They may abscess and drain pus and blood.
