Perform a Skin Test Before Trying Hair Products?

Hi Doc,
when we buy new hair products for our hair, like shampoo, conditioner, etc, is it necessary to do a skin test? This is because some products may be sensitive to a person’s scalp?

Yes, that may be a good idea, but most commercial products are designed to by hypoallergenic (low sensitivity for a reaction). It is generally safe to use almost any known brand on the market today.
