I have white scab like things under hair follicles on my inner thighs. this area used to have red spots on the hair follicles which are now white. they used to be itchy and cause a burning sensation. what can the white scabs be?

Keratosis pilaris: More often seen in children but also possible in adults, hair follicles can respond to chronic inflammation from conditions like eczema by producing excess keratin. This produces a white, rough substance over each follicle that improves with treatment of the underlying irritation. In some situations, salicylic acid-based scrubs are helpful as well. This is one possible explanation.

Healing folliculitis: Folliculitis is an infection in hair follicle. It commonly occurs on areas where friction occurs. It usually starts as little red spots, which may itch or burn. These develop into pustules (lesions containing a tiny amount of pus). These pustules are often healed spontaneously by your body and appear as yellow or white scabs during the healing process. Wash gently with antibiotic soap and water.
