So Far So Good!
I found this product from a Youtube video by Bryan Johnson on gray hair. My mom has jet black hair, but finally started to grow some grays. Pros: - Fast Shipping. I live in the USA and it shipped from their Poland warehouse fairly fast. - Instructions are clear. Do not wet your hair for first 7 days, and continue with regular routine after. This was the hardest part for someone who is used to washing at least 2x/week or every other day. - So far, the grays have started to reverse on her head! I was pleasantly surprised at how effective it is. Cons: - The formula has an odd almost vinegar smell, so you would need to maybe mask it with something else like leave-in-conditioner at the tips of your hair - BOTTLE DESIGN. (This is the reason for the 4-stars insteads of 5). The product spills quite a bit due to the bottle not having some sort of nozzle or application to put directly onto the scalp as required, which results in losing a lot of liquid when you try to use it. For the cost of the product, I think the company should invest in better bottle applicators so customers benefit from the entire product without losing liquid volume. Overall: would recommend to give it a try. I bought four (4) bottles and looking forward to seeing how my mom's hair turns out once she's done with all of them :)
