There are a lot of products out there — conditioners, serums, shampoos — that promise to heal and restore dry, damaged hair. Sadly, there's really no way to heal damaged hair. Hair is not a living tissue with regenerative abilities, so it can't heal. It has no nervous system, blood, or living cells.
Using products that are designed to nourish the scalp and hair can definitely speed up this process, but on average you'd be looking at six months to a year to fully see a difference in your hair's condition.
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.
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.
Depending on their size and cause, scabs usually fall off within a few days to two weeks.
Hair loss may occur when scratching is aggressive or the scalp condition affects the structure or strength of the hair follicles. Once the underlying scalp condition is treated, the hair usually regrows.
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.
What can cause sores or scabs on the scalp? Sores or scabs on the scalp are often harmless and clear up on their own. However, they can sometimes be a sign of a condition that may require treatment, such as psoriasis, contact dermatitis, or head lice.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
What Can Damage Hair Follicles? Several different issues can affect your hair follicles, from hormonal and genetic conditions such as male pattern baldness to infections, inflammatory conditions and even physical damage from certain styling products, hairstyles or treatments.
“A healthy scalp should be clear of flakes and irritation or redness, and it should be free of dryness, or any signs of infection, or disruption of the skin on the scalp.”
Effective treatments for some types of hair loss are available. 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.
Wearing your hair too long will make it look thinner
"Ironically, with thinning hair it's important to make sure you get your hair cut regularly," says Julie Hensman, from Hensmans in Northampton. "Thinning hair can get out of shape more quickly, making it look more obvious".
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.
Sores, blisters, or bumps on the scalp
Painful sores, blisters, or bumps that develop on the scalp may be caused by: Infection of the hair shafts (folliculitis) or the skin (such as impetigo). An allergic skin reaction (contact dermatitis). Viral infections, such as chickenpox and shingles.
Answer: Hair growth in scabs
It sounds as if you are still in the process of healing. The hair follicle will usually grow a hair back if it is not destroyed/injured in the process of the flap/surgery. You will be able to assess the situation better after the healing process has finished- this can take up to 4-6months.
Scarring, or cicatricial alopecia, is an inflammatory condition that destroys hair follicles, causing scarring and permanent hair loss. The Mount Sinai's Alopecia Center of Excellence can help. Dermatologists have deep experience diagnosing and treating this form of alopecia.
