Nisim F.A.S.T. Fortified Amino Scalp Therapy Shampoo, 10 fl oz - Supports Faster Hair Growth with Essential Nutrients, Amino Acids & Proteins - Sulfate, Paraben-free

I bought this since I'm growing out a short pixie. I've been using it about 6 weeks. I don't have a baseline so I honestly can't tell if my hair is growing a lot faster, but it's growing nicely. I like the scent. I still have short hair so I need to use very little - so even though it's expensive, I don't mind buying it. You need to use a conditioner, but use any conditioner you like. My hair is silky soft since I started using FAST. It might be due to the conditioner (I started using Tresemme Botanique at the same time), but the results are good so I'm going to keep using FAST too.I'm a person who never leaves reviews, so if I'm leaving a review it means I'm very happy with this product.

It makes your hair grow

Love that it helps my thin fly away hair. I used to sell it in my salon when I was still working

I have only used this product two times since the purchase. So far, I am happy with it.

I bought this product with the conditioner (separate purchases) for what the product promised: to grow out my pixie haircut faster.1. The Fragrance: Past reviewers did not like the fragrance, but I really liked it; there is no fragrance (a lot of reviewers said that it smelled like a cleaning product - it does not). I don't like perfume-y shampoos or conditioners so I really liked how this shampoo cleaned your hair without any foo-foo scents.2. Function: Initially, I purchased this shampoo to grow my hair faster, but then used it every other two days for its cleanliness. This shampoo cleans your hair! My first wash with this shampoo, I was impressed. I felt that the shampoo did not create its own buildup, but actually cleaned the buildup from other products. My hair was shiny and had a bounce to it. I honestly feel that this was the cause of this shampoo, but I also purchased the no sulfates or parabens one (apparently there is one that has sulfates).The main question that everyone wants to know is if this shampoo actually grows your fast. For this shampoo to function properly (to grow your hair faster and longer), you have to use it with the conditioner every day. You have to use the shampoo twice and then you condition once, wait 5+ minutes before rinsing. In essence, it is a long process and although, I felt that my hair was cleaner with less buildup, I did not experience a drastic length in my hair that I noticed.Another concern that reviewers had was if using the shampoo and conditioner every day as well as having to use the shampoo twice before conditioning, if it would create buildup and damage for your hair. I tried this process every day for less than two weeks and did not experience dryness or damage. It is important to purchase the no sulfates or parabens shampoo and conditioner though, if you plan to wash your hair every day with this product(s).3. Price: I would buy this product again because it does clean your hair and gives your hair the bounce and shine that your hair needs to be healthy, but it is expensive because I did not purchase the shampoo and conditioner in a bundle (I could not find one on Amazon). So again, I will most likely not buy this shampoo and conditioner, but only because of the price, not because it dries or damages your hair.I really liked this shampoo and conditioner. I would recommend it to someone else if the price wasn't concerned. The shampoo and conditioner functions as a shampoo than other shampoos which seem like foo-foo shampoo/conditioners compared to F.A.S.T.

I love this! I'm only a month and half into using and can't claim I shampoo and condition my hair EVERY day. However, most days I do use the products. My hair is softer and less tangled. I have way less of those fairy knots in my 4A/4B hair. I haven't blown out or stretched to see if I have add length to my hair but I'm happy. I have come to the conclusion the products are so expensive because they are great and you will only go through a bottle every 4 months to 6 months. I use a quarter size of shampoo to wash my hair and 4 to 5 pumps of conditioner. Mine was already a half inch above my bra prior to beginning. In 6 months or so I will update with photo of my growth. If it has occurred more than naturally would have happened...

I wanted to give this product no stars but Amazon makes you give at least one. I used this product once exactly as the bottle says and it completely washed out my hair color even though it says safe for color treated hair and sulfate free. It was horrible! Do not use!!!!!

Took a little while to get used to. First few times it made my hair very dry and nasty feeling once I rinsed it out. I was scared to comb through it with a wide tooth comb in fears my hair would break off. Actually after I finished off the bottle and went back to my regular shampoo, my hair grew faster. Once about half way through the bottle, my hair seemed to accept it better and not feel so knotted...but still dry. I had to follow up each time with a very good deep conditioner under a heating cap. I wouldn't buy this again.
