Kerasis Scalp Care Serum

I apply this serum when my scalp itches or feels like a breakout is about to occur. It contains keratin, ceramide, and tea tree oil, so it is a moisturizing product with a soothing effect. The nozzle is long, so I can simply squeeze it directly onto the affected area and rub it in. It doesn't leave a greasy residue on the scalp or hair, and it absorbs well.
