Following are example user reviews (edited for style), selected for their anecdotal insights on product form and function.
For kinky, coily 4c hair, length is one of the struggles we face. This lengthen booster shot specifically takes care of that. I mixed mine with the moisturizer and I am excited to see the results over time.
I love the idea of adding amazing ingredients to my hair shampoo that will nourish the hair and help it grow fast. I will continue to use the shampoo with the booster shot to get my hair longer and healthier after postpartum.
I really like these little pods. They are fun and easy to use. Mess free. I hope this helps for hair growth.
I love how easy and convenient these little booster shots are to use, and put right into the hair products. I used the volume in my shampoo and I added the lengthening into the conditioner. This is the first time trying this line and I love it. These products make my hair look soft, shiny and healthier.
