Great stuff

Awsome shampoo and Conditioner That Really helps your hair Grow and Thicken my Hair hasn't looked this Great in a long time I'll stick to this Product now Thanks .....

my favorite

I love this shampoo & conditioner - it makes your hair appear thicker after a wash, as well as slick and shiny. It tames my frizzy hair nicely, something no other shampoo can do. A bit pricey for me to buy all the time, but it's a nice treat.

Great products

Started using shampoo a few months ago as hair very thin.. My hair seems fuller with new growth now all over. Family members have commented on how full my hair is looking👌👌
Love your products. Have recommended to friends..Am also loving conditioner that I started using last month.

Shampoo and conditioner

Been using for a while. Great results.
Have referred several friends and work buddies who say the same thing. Great products.
Hmmm…..must be time for a spitters fee 🤣

Love your product. My hair seems fuller with new growth at the front where hair was a bit sparse.

Have been using this for quite some months, nice smelling shampoo and do like it but need try something else new.

Truly a good shampoo, after having loss of hair and trying different shampoos recommended by a specialistI with no results. I started searching for a science approach, I eventually found this shampoo and started using it two years ago. The results were slow but positive and now my hair is thicker and growing faster and I no longer have an itchy scalp the shampoo leaves my hair soft and shiny.
I don’t need to use conditioner with this shampoo.

Makes my hair feel very healthy smells beautiful

Luv this stuff smells so clean

Happy with the product

I’m happy with both shampoo and conditioner so far. My scalp is healthier and I’ve noticed some hair growing. :)

Hair growth hope

Hair feels and looks lovely but there is no sign of new growth.

Really good product

Very satisfied with the results. My hair & scalp feel healthier. My hair feels thicker & I notice some soft hair regrowth. Happy to keep using the shampoo & conditioner. Love that it’s natural too

Happy hair but when are the refills coming?

This shampoo and conditioner is wonderfully nourishing for my hair, yet so lightweight. I am a repeat customer.
The only thing I want to know is when will you release a refill pouch?

Great Product

I have fine thin hair and it’s never been easier to manage than now with this combination shampoo conditioner. Three years in and no plan to change.
