Topical Minoxidil: Hair Growth Agent

Contact Dermatitis and Amount of Minoxidil

If you have contact dermatitis on the scalp. you had better reduce the concentration of a minoxidil solution.

The amount of ingredient is the same between 1mL of 15% minoxidil solution and 3mL of 5% minoxidil solution. The efficacy of hair thickening will also be the same between these two doses.

However, there will be more possibility of irritation and inflammation on the scalp with higher concentration minoxidil solution. There will be less incidence of contact dermatitis by using lower concentration minoxidil solution.

The author recommends to reduce the concentration of a minoxidil solution from 15% to 5%, when you resume applying a minoxidil solution after the treatment of dermatitis.
