I started with the oil first and could see a difference after a couple of weeks and decided to try the shampoo and conditioner. I went full grey during the pandemic, and have been frustrated with the lack of body and frizziness that I never had before! Ive tried multiple products trying to tame it but nothing has worked. I’ve been using the s&c for about 2 weeks now and I can see and feel a difference. It’s not great yet but I’m hoping as I continue to use it, my hair will get even better over time.
