About 4 months ago I had some red/copper low lights put in my hair. Within about a week I developed several hives/blisters on my head, the worst of which was towards the back of my head where 3/4 seemed clustered together. About 3-4 weeks after this my hair fell out from that particular area (about 3-4 cms across). I’ve been to my GP who wasn’t very helpful and said it may or may not be an allergic reaction, and she did not know why the hair had fallen out. It’s now 4 months later and I appear to have some regrowth but it’s like baby hair, very fine and short. I can feel it with my finger but it doesn’t cover the bald spot as I have very dark brown hair. Will my hair return in time, and what process does it take? Is it normal that the hair appears like baby hair? It may be an impossible one to answer, but roughly how long before the bald spot is covered and looking like my other hair?
I notice that most sites suggests hair grows on average 1/2 inch per month. Is this growth rate the same for hair that has fallen out and is growing back? I’m desperately looking every month for signs of 1/2 inch growth but wondered if the rate was slower/quicker for brand new hair. Thanks
This is a tough hair loss question not only because it is tough for you to go through, but also because it is difficult to diagnose without an exam. You need to see a dermatologist or a hair loss specialist (but definitely an MD) so they can look at the spots with hair loss on your head. The reason is that the hair loss pattern and sequence that you describe could have been caused by many things including 1) a chemical alopecia (reaction to the chemicals used on your head) 2) an allergic reaction, 3) an infection of the skin on the scalp (by anything from a bacterial, fungal, or a viral source), or even 4) Alopecia Areata. Often, only a physical examination by a doctor and testing (sometimes including a scalp biopsy for microscopic analysis) will determine the cause.
The good news is that in most all the cases I have listed, the hair does grow back although it is impossible to predict how long it will take without a definitive diagnosis. In the meantime, see your dermatologist or hair doctor, stay away from the chemicals for hair, and take a photo to document for yourself how the growth is going.
