When I was younger my hairdressers sold me a shampoo that didn't suit me, it made my scalp very itchy till the top part of my scalp I accidentally scratch it till now there is lump scar there.

Now when I go for haircut (of cause no longer the same salon that sold me that shampoo) there are times when the hairdressers notice the lump scar I see their facial reaction will get gross out from noticing it.

This make me feel self conscious every time I get a haircut. Also who knows in future I might get bold which is worst bcs now everyone can see it and get gross out by the lump scar.

Would like to know is there any safe treatment available that can remove or reduce the appearance of the lump scar???
