Volumizing & Thickening Biotin Shampoo & Conditioner Set - F.A.T.T. by Big Kizzy, Gentle Hair Care Safe for Extensions, Color & Keratin Treatments - Strengthens & Nourishes Fragile Hair

I love this product and have been using it for a couple of years now. It’s thickener really does the job

I have no idea why this brand is so amazing, but it is. I was so surprised as I was just shopping for a decent hair care brand that is friendly for extensions because mine kept slipping out. This line was so amazing, my hair was so slick and soft after using it. It smells great, and has been the best product I have found yet. It cleanses the stickiness and goo out of my extensions that are tape ins, which can happen from time to time. It also leaves my scalp cleaned and makes my hair more voluminous, can't recommend this brand enough. What an amazing surprise this purchase was!!

Doesn’t lather very well. I bought it because I needed to do something about my over processed hair. I had hoped that this would help improve it. Been using it for a few weeks and really can’t tell a difference.

My extensions have not slipped or dried out at all. Doesn't volumize my fine hair at all though. Liked it overall. Not sure if it's totally worth the money though.

This product has dried my scalp so bad.. also it was supposed to be safe for color and hair extensions. First time trying it all my hair color came out and my extensions got damaged. I don't recommend this at all.

I have very fine hair and as many people with thin hair know we are always looking for a product to give our hair life. This product is it! Ive been using the shampoo and conditioner for a few months now. I've noticed such a difference. It has a light bubble gum smell, and it left my hair feeling light weight and much fuller, even when air dried. I can now wash every other day and still have full looking hair.I've since tried their other products and love them. My favorite is the happy hour. When my hair is looking dull or has a little frizz I just spray the ends and it gives my ends life again. I love it so much, I carry it in my purse.This came with full size shampoo and conditioner inside a very cute Big Kizzy bag and some deep conditioner that works great on my dry ends.When I don't have my tape in extensions in, I have my clip in hair and use this product on both. I'm so happy I finally found a product that makes my hair fuller and works as expected.

I did not like it. It left a weird coating on myhair and it wasn’t conditioning. Also made my hair feel greasy sooner so I had to wash it more often.

This is exactly what I've been looking for and I'm in love.I recently permanently dyed my hair red, a week later decided to bleach it, and then proceed to dye it blue. My hair is already pretty fine and doesn't take dying well, so I was honestly just hoping for something that didn't make it look dead and limp.This was my salvation. I'm the kind of person who washes my hair every other day and it works wonderfully. Not only is my hair full, but it's sleek and fluffy and looks fantastic. The best part? It's soft as hell too. I was expecting my hair to be crunchy at the expense of being full, but it's so soft with no loss of volume. My hair feels just as soft as it did before my treatments.I can't promise it'll hold up against more intensive stuff, but so far it's fantastic. Way beyond my expectations. The bottles are a little smaller than I was expecting, but I have short hair so it'll last a decent amount of time. Would definitely recommend!
