My ,,must have"!!

[I received this product in exchange for my honest review] After pregnancy and breastfeeding my already thin hair started shedding in a way that honestly scared me even through my blood analysis was good. Styling became frustrating because I love volumes hairstyles. My hair felt fragile, flat and ti...

Not worth it

For reference I'm a licensed cosmetologist and majority of reviews on this product are gifted. I have 2B and 2A hair, its not super thick but it has been getting thicker the last few years. I can usually wash my hair every 4-5 days, sometimes more if I put no product in my hair. I use clean pillow c...

[I received this product in exchange for my honest review] With consistent use I have noticed a decrease in the coarseness of my fine hair, extra shine and even my scalp is feeling a little bit better. The lather is rich and rinses clean. I have noticed small baby hairs growing after 4 to 5 weeks of use. I am looking for thicker more volume right now I feel if I continue to use the system I will obtain that. It is a very light scent that is not overpowering. I do not feel the gritty residue as I do with some of the hair growth shampoos I have used in the past. I feel if you are consistent with this product you will see amazing results.

Bottom Line Yes, I would recommend to a friend

I think this is an okay product. It smells nice on your hair. I would say that this can be a lot of protein on the hair so don't apply too much or you can get a flakey scalp. Comes out nice but it is thick. Redken is one of the more expensive brands.

Hair Type Straight Hair

I bought this whole system to try due to my very thin/fine hair. I would say it definitely helps improve density of my hair. But in exchange, my hair feels very dry and stiff. Without the products in this system, my hair feels hydrated and is shiny and soft. Using this system makes my hair tangle easily and it doesn't glide thru my straightener anymore. I would also say the products in this system dont smell very good. I don't think I'll continue using the products because it makes my hair feel uncomfortable all day with the dryness, tangles, stick/sticky feeing.

Bottom Line No, I would not recommend to a friend
