I spent a lot of money as recommended by my hairdresser. I bought the whole range of Redken products. I was supposed to see results after the third wash. I seem to be battling more now than before with the previous products I used.
this product fails. bring back deep fuel.
Please bring back deep fuel - this product simply does not do the same job. Please, redken, please bring it back!
Bring back deep fuel if you want consumers to keep using your products.
I have used deep fuel for years. I tried the replacement Strength Builder and it in no way treats my hair like the deep fuel. One deep fuel treatment is better than a whole bottle of the strength builder. This is sad!
This is one of the very best deep conditioners I have ever used. I work in the supply store and I always go back to this product and always recommend this as a great treatment. Everyone comes back sooo happy. Amazing scent, amazing product. Leaves hair extremley soft and bouncy!
Ive used deep fuel for years and have found it does what it claims. However the extreme strength builder leaves my hair very hard & dry, lacking in lustre and unmanageable. This is not fit for purpose considering its not cheap. I would rather pay a lot more for old faithful deep fuel than have the extreme strength builder plus for free. It's not worth even 1 star very poor performance.
As I was stating, I decided to give the Extreme Strength Builder Plus a try and my hairbrush is full of hair again. DOES NOT compare to Deep Fuel. DO NOT waste your money! I gave it one star. In case they change it to 5 stars like I see they've done on some!
I tried the Extreme Strength Builder Plus and was not impressed at all. Does NOT compare to Extreme Deep Fuel. I tried everything for my fried, bleach blond hair. My hair was breaking off and my brush would be full of hair. Then I tried Extreme DEEP FUEL and no more breakage! It was unbelievable how well it worked! I CAN NOT believe they discontinued it. So, I decided to give the Extreme Strength
This product does not produce the same results as deep fuel. Please bring back Deep Fuel, my hair needs it!
