I purchased the shampoo, conditioner, hair mask, hair growth spray, and hair growth serum, and I noticed a difference in my hair almost immediately. The texture and fullness improved right away, but the hair mask stood out the most. It made a huge difference to the ends of my hair, which were always frizzy—not exactly split ends, but they’d frizz up and make my hair look stringy within a few hours. Now, my hair stays smooth and shiny from root to tip all day long! Another major improvement was how well my hair held up after curling it with a hot iron. Normally, I’d need to use a strong hairspray to keep my curls in place, but after just one use of the shampoo, conditioner, and hair mask, my curls stayed intact until the next day without any hairspray at all! I wasn’t expecting that at all, and it’s been such a pleasant surprise. I’m absolutely thrilled with the results so far!
