Customer Reviews

Smooth Lock Shampoo - Heat Protection Shampoo is rated 2.25 out of 5 by 20.
Rated 1 out of 5 by from Not fit for purpose? I had to buy Smooth Lock when Smooth Down was discontinued and, virtually instantly, I hated it. It does nothing for frizzy hair and it leaves an "unwashed" feel. It can in no way be a substitute for Smooth Down, which was the best shampoo I have ever found to control my dry/unruly frizzy hair. Would Redken please explain why they decided to discontinue a product which did exactly what it said on the tin, i.e. "anti-frizz smoothing for very dry/unruly hair". I have tried other shampoos in the Redken range but none give the results that Smooth Down did. Please bring it back, no substitute please!

Rated 1 out of 5 by from Smooth Down original PLEASE I had been using Smooth Down shampoo and conditioner for years and was very disappointed when they changed the formula and scent! I can no longer use the product and had to switch to a competitor product. The original scent and formula was so much better and did miracles for my hair. I beg you Redken to bring back the original. If you just got rid of the "almond oil" which I am guessing is giving it that horrible smell, I would consider re-using your products.

Rated 1 out of 5 by from Not even close I was a religious user of the Smooth Down line and was so disappointed when it was discontinued. This new version is a poor substitute. It may work just the same, but I wouldn't really know, as I can't get past the horrible smell. I can't imagine why on earth this would ever be construed as an improvement. I have a stockpile of the old stuff, and when that runs out, I'll be switching to another brand.

Rated 1 out of 5 by from Be warned, leaves permanent NASTY smell I had used smooth down in the past, so i was excited to use this one since i use heat a LOT. Should've read the reviews before buying because i paid $40 for the shampoo and conditioner and when i washed my hair in it it smelled disgusting! Reading the bottle i found it has almond oil in it! Its been about 2 months and i still can't get the smell outta my hair. I changed my shampoo and returned this opened to CVS. Don't buy! Unless you want hair that is permanently scented like almonds.

Rated 1 out of 5 by from NOT THE SAME! I used Smooth Down for years. I got this stuff thinking it was the same. Not only is the smell horrible, the product isn't even close to what Smooth Down was. I am interested in the competitor brand that others are using because I will be making a change as well!

Rated 1 out of 5 by from Please Bring Back Smooth Down!!! I do not like smooth lock, the scent is horrible and it doesn't make my hair feel nice like smooth down does. Why would redken change this formula?? I read reviews here and on other sites, the majority of people prefer smooth down and do not like smooth lock. Please bring back to good one and dump smooth lock, it's awful!

Rated 1 out of 5 by from Why?! I have been purchasing the Smooth down range for years and was sorely disappointed when it was discontinued. I purchased the replacement product and why you have changed the formula is baffling. There was nothing wrong with the old one. this new product however smells disgusting and does not have the same affect on my hair. Please bring Smooth Down back!
