I have super thick long hair and a stinky oily scalp that I can wash six times and it still stinks. I usually use herbal essence and wash 4 times bc it has the strongest perfume to try to cover the stink. The only way I could remove the stink before was soak my scalp in TIDE once a month. I bought this shampoo bc I remember how good a clarifying shampoo had worked before when I was younger. It would be a lot less stink in the winter months. In summer, forget it, only tide. So anyway, I washed with this 3 times. TWO TIMES ONLY and I could actually feel my hair was TIDE level clean. This is mind blowing to me. I washed again and I swear my scalp feels like normal human skin now without the sticky oil feeling it always has. Better than TIDE clean. After my shower and I was putting my hair up, I noticed that behind my ears and around my hairline also felt so clean and healthy too. You dont even know...to get behind my ears clean i scrub several times with a facecloth and irish springs soap back there. The skin around my hairline never feels completely clean, never. This shampoo got behind my ears clean without me trying. I hope that someone with a stinky scalp like me is able to liberate themselves from tide soaks or just living with the best your shampoo could do like I did. PS, although 3 times got my hair the cleanest its ever been, I will only be doing it twice from now on bc it burns after, the same kinda painless one day burn you get after going blond. I did wash with herbal essence right after too bc this stuff smells like chemicals in a bad way. Anyway I am super super impressed with this shampoo. Also, it activated my curls big time. I paid a little more than im used to but will def be buying it on a normal basis now.

This definitely works for people with oily hair! Usually I have to have my daughter wash her hair everyday but with this she can go one to two days without washing.

This is the BEST clarifying shampoo I've tried. Having years and years of struggling with oily hair this shampoo has changed my hair. It works better than any other I've used.

Bought for my son, wanted to try something new. So far no complaints, leaves hair smelling good and soft.

I will probably only use it once per month and alternate with other shampoos.

Got a deal on this and love it. Its a great all around shampoo.

I really like this shampoo-makes one's scalp feel very clean and hair also feels clean. Texas Gal

Best shampoo ever. Doesn’t leave residue in my extremely long, long hair. Can no longer find this product. So disappointing.

If you have ANY doubts about spending this much money on hair products, don't! These are THE BEST products I've used, ever, and my mom is a hair stylist. I've used tons of crap from Sally's and Shoppers Drug Mart, but this stuff is worth every penny! Thinking of going with the smaller bottle of a Biolage product? Don't! Just pay for the bigger one and save some money overall, because this stuff WORKS!These are all the products I purchased:Full Rescue Thickening ConditionerFull Rescue Densifying Leave-In SprayScalp Sync Clarifying ShampooPurifying Scalp ConcentrateHydraSource Daily Moisturizing Leave-In TreatmentI use the clarifying scalp concentrate while running my bath or starting a shower. I'll put a face mask on too so I get as close to that 15 minje wait time as possible!I then use the clarifying shampoo and thickening conditioner as stated in the instructions. A little goes a long way with the shampoo, and the conditioner just feels so nice on my hair. It's almost like you feel it soften immediately!After getting out of the shower or bath, I use the HydraSource Daily Moisturizing Leave-In Treatment on my lengths of my hair, and the Densifying Leave-In Spray on my roots. THESE LEAVE-IN PRODUCTS DO NOT MAKE YOUR HAIR OILY OR GREASY!!! Holy moly, the liquid just evaporates as your hair dries and you're left with this AMAZING soft, bouncy smooth, shiny, healthy-looking hair!I 1000% recommend these products as a girlie who has medium-medium thick hair, has experienced hormonal hair loss, suffers with scalp acne, and is trying to repair her frizzy curls! I've only used the products TWICE, but I saw an immediate difference after ONE use!

Game changer!!! I've been dealing with some hair product buildup at my roots and no matter how much I washed my hair and air dried/blow dried properly it was feel so greasy. After the first use of this my hair felt like I came out of the salon! No more buildup or product or grease, smelt soooo fresh and felt super smooth. So happy with this purchase! Also a plus that it's abit cheaper than the viral Ouai detox shampoo 😃

This product was suggested by my hairdresser. Works fine for me.

Smells amazing

This helps with dandruff and oilily hair. Highly recommend!!
