I have tried a million 'clean' shampoos. This one is by far the best. It cleans but doesn't dry out my hair. It smells amazing and I love that it comes in a big gallon size to reduce the plastic consumption.

I love this shampoo and have for years. It cleans even oily hair very thoroughly. It can be very invigorating. Do not leave on too long as the mint in it can give you a chill, no really! Smells great, cleans great but you will need conditioner as it leaves the hair dry.

We have been using Giovanni TT shampoo for many years. When we were running low, I was shocked at the prices at various stores. I had gotten bigger bottles from a clearance warehouse previously. Well, that source of course no longer carried it. So I couldn't believe I found it in a gallon at a great price. I'm hoping this online source is still around when we run out again.

I love this shampoo so was so excited when I found such a large size so I can just refill my smaller shampoo container once I finished it.

I actually add a few other essential oils and use as a body wash in addition to being a shampoo.

Clearly, we have a lot of hair in my house so purchasing this size bottle was practical. We have the pumps in every shower in our house and just refill them with the big bottle. Tea Tree smells clean, feels tingly on the scalp, and leaves hair shiny and soft. Excellent product, highly recommend it!

Love, love, love. Besides the amazing certified organic and vegan ingredients, the fragrance, the lack of SLS, the truly invigorating sensation my scalp receives when lathering up, it has completely reversed my dry scalp and dandruff. I've heard amazing things about Tea Tree oil for dandruff and dry scalp. Believe me, IT WORKS. But add rosemary and peppermint to the mix and you have the perfect shampoo to support hair growth and reduce hair loss. I am obsessed! I'm about to review their conditioner as well. When you love something this much AND you can buy the gallon salon size, what could be better? Less environmental waste, too? What a perfect product! Bravo, Giovanni! Bravo!

Who knew you could get a gallon? I love Giovanni T4 shampoo and buying by the gallon means no more scrounging to find deals on it, when it's in stock. It's also way cheaper by the gallon. Now I keep one pump on hand and refill it. Buying is better in bulk.

This Shampoo is simply amazing! It provides a refreshing sensation on the scalp and has a pleasant scent. The gallon size lasts for a remarkably long timegoing strong for 4.5 months with a family of four using it regularly. Highly recommended for its long-lasting value and invigorating experience.

I have a scalp that builds up sebum quickly, and this shampoo does an amazing job at keeping it clean, even with washing every other day. It smells great, feels tingly during washing, and rinses out clean. It also keeps my grey hair looking shiny and bright - no yellowing. Great!
