  2-3% salicylic acid leave on product for scalp. Is it safe?

  Posted by Abdullah on August 28, 2021 at 7:12 am

  Can i use 2-3% salicylic acid at pH 4 in a leave on product for scalp? 

  It is to help people with dandruff and very oily scalp.

  I think 2% is the max for leave on products, and 3% for rinse off.

  @Padmavathi yes but then Paula’s choice has 4% leave on BHA. That makes me confused ????.

  By the way, these are for skin. My question is are they safe for hair and scalp? 

  I had seen somewhere that salicylic acid makes the hair shaft weaker. But i cant find it now.

  Over 3% of SA is considered a drug. 
  Regarding safety, it depends on the pH of your final product.
