Redken’s new Acidic Grow Full System was specifically created for clients with thin, flat hair to experience instantly fuller, thicker looking hair**. This density and strength system consists of a series of lightweight formulas powered by advanced pH science with azelaic acid, caffeine and prebiotics. Acidic Grow Full System works by balancing the scalp with moisture, adding instant root lift, and providing 2x less breakage*** and stronger hair****. The four-step system includes Shampoo, Conditioner, Scalp & Hair Serum, and Instant Densifying Spray. The Scalp & Hair Serum is the star product and is clinically tested to hydrate the scalp***** and promotes denser, fuller looking hair. Redken Artistic Educator Shayna Golet says, “As someone with the finest, most do nothing hair ever, I can say that I do like how this line gave me instant gratification after just one use with the system after my hair was blown out. Big fan of instant results over here.”

How to feel the fullness:
- Start with the Shampoo and apply to damp hair, lather and rinse
- Follow up with the Conditioner, starting in the mids to ends and continue to distribute towards the scalp. Use an amount appropriate to the hair length and density. Leave for 3 minutes, then rinse well.
- Next, the Scalp & Hair Serum, which instantly rebalances the scalp with moisture, is applied directly onto the scalp by sub-sectioning the hair. Continue to sub-section and work towards the top of the head. Repeat on the opposite side and back of head. 1-2 sprays per section is adequate. Use fingertips and massage into the scalp. Do Not Rinse.
- Last but certainly not least, the Instant Densifying Spray is applied to provide immediate fullness and lift. Starting above the ear, mist product from 6 inches away to mids through ends. Continue to sub-section the hair working from bottom to top of head until all sections are complete. Comb product to ensure even distribution. Do Not Rinse. This product also provides heat protection up to 450 degrees Fahrenheit, which is perfect for any additional drying or styling with tools for a completed look.
We know thin hair can be a sensitive topic, so here are some conversation starters to use with clients who you think could most benefit from Acidic Grow Full System:
- “I’ve noticed that over time that your hair has lost some of it’s density. Have you noticed this too? If I could offer you a product system to address this concern-would you be interested?”
- "In order to help achieve the look you’re wanting today, it will require a bit more volume than you have naturally. Are you interested to find out how we can achieve this look more easily?”
- “I know how much effort you put into your image and beauty regime. One thing we haven’t ever spoken about is your scalp health. We just got a new product system that specifically addresses this topic for you. Would you be interested to learn more about this?”
- “I know we’ve spoken in the past about how to make your hair look thicker. I finally have a new product system to specifically address this concern. Do you have a few extra minutes for me to share these range with you today?”
Thin hair is a common side-effect of GLP-1s, and with the rise in usage of the weight-loss drug a solution for providing fullness is even more necessary. When using Acidic Grow Full System, 91% of GLP-1 users agreed that hair feels thicker*****.
The new Acidic Grow Full System from Redken is the perfect solution for providing salon clients with density and strength for instantly fuller, thicker looking hair.
