I LOVE all things NatureLab, and this one is no different. It’s easy to apply, just wet your hair and squeeze it section by section onto your scalp. I like to rub my scalp a little once it’s on there just to make sure it’s absorbed and distributed throughout. Then you wait 2-3 minutes and rinse. I like to wait til I start to feel the tingle- it creates this really great feeling, cool tingle on your scalp a little while after you apply. The scent is out of this world- I don’t know how to describe it- but it’s very fragrant. It leaves my scalp feeling so fresh and clean.
