It does the job of washing your hair, but when it comes to regulating sebo levels - it doesn't. I purchased this a while back and it worked wonders, so I'm wondering if this time round it's because of a formula change. All in all, quite disappointed with this and it did work last time. Might repurchase from somewhere else in hope they might stock the other formula still(?!)

I have embarrassingly oily/greasy hair, I wash it in the morning then around 7 hours later it gets greasy. The first time I used this, my hair was actually still clean looking the next morning, I couldn't believe it! It hadn't gone greasy in 24 hours! The smell isn't the greatest as its a treatment shampoo but it's not awful, not too strong a smell either. I was highly impressed with this and il definitely be buying it again! It's nice to go a whole day without my hair looking or feeling totally greasy!

I have been plagued with oily acne prone scalp (no dandruff) for the last 3 years where my scalp itches so badly that I often crawl out of bed in wee hours of the night to shampoo my hair. I have tried a wide range of shampoos, ( Aveda Invati, Kerastase, Pregaine, Rogaine, Selsun, Organix, Sebastian, Oribe, Living Proof, Percy & Reed, Nioxin, Paul Mitchell to name a few) consulted doctors and scalp specialists. Oral supplements and medication offered temporary relief. This shampoo is runny, has a light pleasant scent which does not linger after wash. It is gentle and does not dry out my hair yet keeps the sebum in check, no more scalp scratching, acne has reduced by 80%. My scalp and hair is in a calm state. Comparing performance and price to products available in the market, this is an all rounder performer.
