Rebuilding damaged hair is no easy task. Nearly a decade ago, my sister and I were both on Accutane for our acne. While it miraculously cleared our skin, it tragically left our hair completely dried out. My sister took it a step further and dyed her hair while still on the medication, which only weakened and thinned it more. After spending almost ten years testing some of the top haircare products on the market, I’m happy to say we finally succeeded.
Out of the dozens of products I’ve tried, Redken’s Acidic Grow Full System has completely revitalized my hair. Within just a couple of weeks, my hair feels smoother, fuller and healthier than it has in years. If you’re searching for a new shampoo and conditioner, you definitely need to try Redken’s Acidic Grow Full System.

What makes Redken’s Acidic Grow Full System stand out?

The complete Redkin Acidic Grow lineup includes four key products formulated with a powerful blend of azelaic acid, caffeine and prebiotics. These products work together to gently cleanse, nourish and revitalize both the scalp and hair.
Redken specifically designed and tested this complete system for GLP-1 users experiencing medication-related hair loss or thinning. In consumer testing, an impressive 91% of GLP-1 users agreed their hair felt thicker when using all four products. For best results, experts recommend applying them in order: start with the Shampoo and Conditioner, follow with the Scalp & Hair Serum and finish with the Instant Densifying Spray.

What are people saying about the Redken Acidic Grow Full System?
The Redken Acidic Grow Full System has a nice 4.7 out of 5 stars average rating on Amazon with hundreds of reviews. Check out a couple of standout reviews below:
“I suffered from a lot of stress/hormone related hair loss. This product was recommended to me by my hair stylist. It was a good price, came quickly, and smells great. I love how it has changed my hair for the better. I am seeing new growth that is soft and healthy,” one Amazon reviewer wrote.
“I've used this product a few times, but every time I use it, my hair feels thick, it is shiny, and it looks full. I haven't noticed crazy hair growth, but it makes my hair feel like I've just left the salon: thick, clean, shiny, and my scalp is less oily for longer. I can go two to three days without washing my hair vs my normal one day break because it doesn't cause excessive greasiness. Investing in good hair care products definitely ensures effectiveness,” another wrote.
