I strongly recommend tea tree shampoo bar for who has oily hair ...
Gave it a try for my husband. He shampoos everyday but sometimes his hair looks oily in the mid day.  He has tried tea tree shampoo bar for a week, at the end of day, his hair looked fluffy and clean. I touched his hair it was soft. He didn’t feel too dry or any discomforttable on his scalp unlike some commercial chemicals shampoo. I strongly recommend tea tree shampoo bar for who has oily hair problem.
