I really wanted this to work, but it took 2 leave in conditioners and oil to comb through my hair. I have very healthy hair and have never experienced this from bar shampoo and conditioner, and I've used many.

hairdresser saw & felt difference :-)

Love both shampoos (bought Ageless Harvest also) . . . BUT, conditioning bar is N0T enough for my post menopausal, i live in the dry desert hair...

Like Shampoo- on the fence with conditioner

I really like the scent- it is pleasant and not too overwhelming with the mint smell. It smells fresh and clean. So far I like the shampoo bar. It lathers like a regular shampoo and rinses out easily. It has not been long enough to tell if there are differences to my hair but I will definitely keep using it. One reason I bought it was because I thought it might be easier to travel with and more cost effective that trial size shampoo bottles when vacationing.

The conditioner- not sure I am a fan. I like to condition so my hair feels nice and smooth and is easy to comb out. Not sure the bar gets my hair to the softness I like and I find it harder to comb out after I shower than with a regular conditioner. I will keep giving it a try and experiment with how I get it on my hair and how long I let it sit before rinsing. Regrettably, I feel I might need to double condition with another product. So so on the conditioner bar.

I would rate the shampoo alone higher but the conditioner pulls down the rating for me as a set.

Clean Shampoo & Conditioner Duo

I enjoyed using this shampoo and conditioner set from Tree Bottle. I love that they are free from plastic bottles! However, I find it a bit ironic that they are claiming to be plastic free while the two pack comes shrink wrapped in plastic. That was a bummer. Just use a box!

The shampoo cleaned well. The conditioner was less effective. I love that they both scored well when I ran them through the Yuka app for clean ingredients!

Great shampoo, Okay conditioner

The shampoo is Great! My hair feels so clean. The conditioner only works well if I use it has a leave in... if I wash the conditioner off, it is as I never put it on.

Not a fan

The shampoo has a good lather, but the conditioner is like nonexistent. Both leave my hair feeling dry and brittle with rough ends. Not a huge fan, been using it for a couple weeks thinking it will get better as I detox from other products. No such luck

Would not recommend

Shampoo bar is like an exfoliation bar but for your hair? Really strange texture. And the conditioner bar just doesn’t work. Disappointed :(
