My hair thinned because I got it bleached. It won't grow back. What can I do?

Hello, Thank you for your question. First of all I recommend you to go a dermatologist. Chemical treatments could harm your hair but your case is quite serious. Chemically damaged hairs will regrow after 8-12 months otherwise that means you damaged your hair roots.

It may take 6 to 12 months for damaged hairs to grow back.  If you are concerned it is best to see a doctor for an examination.

I suggest seeing a hair loss expert to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like PRP/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

I am sorry this has happened to you.  If the bleach has damaged the scalp, it has been seen that some chemical treatments can indeed permanently effect hair growth.  I would highly suggest seeing a hair restoration specialist to be evaluated for nonsurgical and surgical options. 

Hair loss  can occur following the use of chemicals. This can be in the form of hair breakage or shedding which can be usually recovered after 6-12 months. But, it will be better to get a physical examination by a hair specialist doctor to know the exact extent of the damage and the treatment of the same..

Typically hair injured by chemical treatment grows back in 3-6 months. Hair grows at the rate of 1/2 " month once it starts growing so if after 2 years it's not happening, I suspect that you may have some other reason that caused your hair loss but was masked by the bleaching. There are so many causes of female hair loss to get to the root cause will require a workup by a hair loss specialist or an endocrinologist. The longer you wait, the more difficult to restore, so seek expert advice ASAP. 

I can't emphasize enough just how important it is to get expert advice. There could be one or more things going on.Reactions to bleaching, dyeing coloring are common - and becoming more common in my opinion. I've written extensively on this topic.What can bleaching do?1. It can sometimes cause no problems. This is the most common scenario.2. It can sometimes cause hair breakage. After all the damaged hairs are cut and allowed to regrow, the density returns back to normal.3. It can sometimes cause shedding. The hair sheds 2-6 weeks after bleaching and then regrows.4. It can sometimes cause shedding which speeds up the unecessary use of hair growth cycles which speeds up the age at which a patient notices they have genetic hair loss.5. It can sometimes cause scarring hair loss. This is permanent.Without seeing your scalp, I can't say which is going in. But see an expert. I often biopsy these hair bleaching reactions to evalaute for inflammation and scarring.

First let me say that it is important that you stop bleaching your hair for a while to allow the hair to return to it's natural state.  For thinning PRP hair therapy yields great results and helps hair regrowth.  You may also want to utilize a cold-laser that bio stimulates hair follicles. A good one that is FDA certified and has science backed results is LaserCap.

If it does not return to normal within 8 months, then you may have permanently damaged the hair roots, See a doctor
