F.A.S.T Fortified Amino Scalp Therapy Shampoo 1000 ml – Sulfate & Paraben Free Hair Growth Shampoo for All Hair Types, Amino-Enriched Formula for Longer, Stronger Hair

Love this shampoo. I have super fine baby hair which never seems to grow and which had gone to look a bit lacklustre over the past few months. I had previously used the product but foolishly stopped when it ran out! Thought I would revisit this product again and within two day the condition and appearance of my hair has changed dramatically. It looks smooth, healthy and shiny. I only use the shampoo and know it did make my hair grow last time but had forgotten as to how much it actually suited my hair. I won’t be making the same mistake twice and will always have a spare! It isn’t a cheap product but I guesss with this you are getting what you pay for, good quality, paraben and sulphate free which actually requires a much smaller amount as it lathers beautifully meaning you use less on your hair and it lasts longer. The fragrance still reminds me of the monkey house at the zoo, but in a pleasant way...a sort of tropical floral aroma which you can smell when you swish your locks after drying.

Works really well… the 2 photos are taken 9 months apart ( had 1 haircut during those 9 months ) . I used 2 or 3 times a week and occasionally less to give my hair a break as I find it quite drying. I think that it’s grown quite a lot over the 9 months. Wanted something to help it grow as decided to grow the colour out after 35 years of colouring with box dye . Have purchased lots of bottles of this now and will continue buying

If you want your hair to grow buy this, I actually think that it works really well. It is a little pricey but I think it lasted me for quite a while. Not so keen on the conditioner so I use my own for that but would recommend the shampoo. Comes in a pump bottle so easy to use in the shower.

This is the first review I’ve ever felt compelled to write but if it helps atleast one other person then it’s been worth it. After a hair colour disaster and some ill placed extensions my hair was snapping off, weak and just looked terrible. It’s a viscous circle. You don’t like your hair so you get more extensions or dye it a bit more but enough is enough! Winter is a perfect time to repair the damage and grow some hair back so I purchased this product on the strength of its reviews. When it first came I was dubious, how can a shampoo help your hair to grow? But I went with it, at this point I had nothing left to lose. The shampoo doesn’t smell wonderful but it’s not terrible either, I’ve come to quite like the smell. I would also agree with other reviews that the shampoo makes your hair feel strange when it’s wet, however, once dried it’s the softest it’s felt in a long time. I’ve been using a thick conditioner and some leave in treatment. I’ve also been tying my hair up and trying not to use heat where possible. I started using this shampoo daily 2 and a half weeks ago and the results speak for themselves. It may not seem much but my hair is usually super slow growing! I will be purchasing again and again and again until my hair has grown to a length I’m happy with but for now 5* buy it you won’t regret it! ❤️

I had my hair cut way to short for my liking- the picture with shorter hair is in Jan2021 and the other one is in Oct2021 This shampoo is a miracle. My hair would normally gets to the length it is right now in 2 years. The shampoo made it happened in less than 1 year. The hair looks healthy and shiny- i do recommend using a mask after washing the hair Initially i was washing my hair every other day, now twice per week. It is expensive but a bottle lasts for months. I do recommend this product

Haven't seen any growth or improvement. Will update rating if there is a change.

Used this shampoo multiple times over the past 5 years and it really has helped my hair so much. I’m a hairdresser and I dye my hair often and wear extensions occasionally, without using this shampoo I have to touch up my roots every 7-8 weeks. When using it 2-3 times a week my root touch up was every 5-6, and when using it 4-5 a week my root touch up would be 2-3 weeks. My hair has grown so much from using this. I don’t bother using the fast conditioner, just use a moisturising conditioner as the shampoo is very drying.

I've been using this shampoo since the 3rd March so roughly 2/3 weeks. As results are meant to show after a month of usage, I can't comment on the hair growth (although I do think my hair has grown more than usual, even though this could well be the placebo affect!) My hair has felt soft and fuller and I haven't experienced dry hair. The smell of the shampoo is not unpleasant but it's not nice either; due to this I often shampoo first with Fast then with a nicer smelling shampoo. I don't use the Fast conditioner as I can't imagine the conditioner will have much affect on hair growth which is what I'm primarily using this shampoo for. Instead I tend to finish with an intensive conditioner as my hair is thick and quite dry-your average conditioner doesn't really do much for me. I've recently started using sulfate free shampoos and conditioners and I do believe they leave your hair softer, shinier and fuller and this shampoo definitely does that. I will do an update in around 2/3 weeks time to talk about any hair growth, etc but for now I'm quite happy. If you're interested in buying Fast shampoo then I would definitely save money and just buy the shampoo as the conditioner won't do anything for hair growth-get a decent conditioner for under a fiver and just use Fast shampoo everyday!

My hair grew slowly. It was fine and delicate. I've been using FAST for years now. My hair averages an inch a month! I'm 56 years old, and I have a thick, healthy, long head of healthy hair! I do not get buildup, but still use a clarifying shampoo once in a while.

It was a wonderful clarifying shampoo. It does dry your hair out thought so you will need a really good conditioner but I really like it. Growth- I haven't noticed any change in length.

Good

Love this shampoo/conditioner! It makes my hair feel great , soft, & shiny and my scalp feels better too. The scent is alright all tho it could be improved. Spendy, but worth it. And I think my hair did grow faster! I just bought the lrg size. That should take 2 yrs to use! After 4 mos I'm still using the first smaller bottle. I ordered the sulfate free. Give it a try.

I may have worked. Nobody wants to have to wash their hair every single day. It's ridiculous. They need to come up with a better formula or a leave in conditioner that keeps working or something.
