Feel Fuller Duo

Customer photo review of Feel Fuller Duo

I really enjoy using these. They smell pleasant and not too overbearing. My hair feels lighter, softer, with a little more volume. I would highly recommend them.

Customer photo review of Feel Fuller Duo

I like ok but it does not dispense enough.

Feel Fuller Duo

Customer photo review of Feel Fuller Duo

This is an amazing duo that literally saved my hair. It was badly shedding after a chemical over-processing. I was afraid to loose my long hair completely, none of the products I tried worked. Dr. Gary suggested using his Feel Confident Shampoo and Conditioner. There was a noticeable improvement within two weeks. Shedding completely stopped within a month. I will continue using these products to maintain healthy long hair.

Feel Fuller Duo

My hair feels more manageable

Feel Fuller Duo

I really like the shampoo's natural smell.

Feel Fuller Duo

Love this duo. The combination of shampoo and conditioner is a great texture and leaves the hair feeling light but fuller.

Feel Fuller Duo

Works very well for my hair. It doesn't weight it down and the scent is light and fresh. I have seen regrowth after 2 months of use which led me to subscribe! Very happy.

Feel Fuller Duo

This product turned out to be much better than I expected. I like how it leaves my hair smooth to the touch. The smell is pretty darn good too, especially the conditioner. You can feel a light tingling in the scalp as you let it set for a couple of minutes, which id imagine is a good thing. I have to say, although it’s a bit pricey, this has become my favorite shampoo and conditioner.

Feel Fuller Duo

hair-scalp feels healthier!

Feel Fuller Duo

Everything feels right about this product. Clean ingredients leave my hair without any residue, drying, or frizz. I love it.

Feel Fuller Duo

I feel like the product is making a difference and making my hair appear thicker and fuller. Crown looks better and my barber has mentioned that my hair has gotten thicker.

Feel Fuller Duo

Improved thickness. Great to use in combination with finasteride/monoxidil.

Feel Fuller Duo

Great products. Noticed a difference in my hair almost immediately.

Feel Fuller Duo

I started the shampoo and conditioner at the same time as taking medication so I can't speak to the results of hair growth or thinkening, regardless I love this product. I have had an ichy scalp my entire life and with this shampoo I no longer have that problem. I have long hair and the conditioner makes combing through my hair easy, detangling my hair.

Feel Fuller Duo

I love the shampoo and conditioner. I saw a difference much sooner than I thought. Even my hair dresser noticed the difference, and commented on how fuller and healthier my hair felt.
