Hello all, Can anyone tell me if it's okay to use menthol crystals in leave-in hair care products, such as hair serum, conditioner, hair gel etc. or would it need to be in wash-out products only (e.g. shampoo). Thanks in advance for your help.
@heavenly4u I have used menthol in scalp treatment(leave on) at 0.2%, you can also look at menthol derivatives for cooling effect and reduced irritation from Symrise, trade names are Frescolats
