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 have a very oily scalp, this product really helped to control the oil production. It's true when they say recommended for flat thin hair
Redken Shampoo
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.
Eh…just ok.
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.
Not it

I received this product for free from Redken in exchange for my honest opinion. I had really high hopes for this line up of products made specifically for hair like mine, but it fell flat (ha). I can achieve similar results with my regular products and my regular products don't leave my hair feeling gross and dirty like these did.
This shampoo, conditioner and leave in spray is phenomenal!!
