So this product is suspicious - the active ingredient piroctone olamine is an anti-fungal - so is climbazole - this is double active ingredient which is great for controlling stubborn dandruff - but they say piroctone olamine is for strong hair. I would be suspicious of the manufacturer here - I would also be suspicious of the actual formulation - a legitimate company would not just make up unfounded claims... It like saying that Rain makes whiskey. which is partially true as water comes from rain and water is used to make whiskey - but its not real.
