Great product!!! Have been using for 3 months.My hair was thinning alot when I washed it, 2-3 times per week. Wow what a difference, minimal hair loss now. Be patient it took 3-4 weeks to see results.I started with one scoop every morning in my 8oz hot coffee now after 2 months started using approx 2 scoops in 12oz hot coffee daily (as it is recommended). There can be a mild taste to it if you don't mix in enough hot liquid. I do not notice and change to the taste of my coffee. Also this one mixes and dissolves completely in hot liquid. As far as my skin, I have not noticed any difference or improvement. I have combination skin and have occasional mild breakouts (1-2 pimples every month). It is a bit costly but worth it.
