I bought the pitta growth set (shampoo, conditioner, serum and gummies) which came with a free gua sha comb 4 months ago for targeting a thinner hair line, parting etc.
The gummies do take some getting used to for the taste but they aren't awful. The other products are lovely, have a nice texture and smell - don't be put off by the lack of foam from the shampoo, you really don't need that much. I have had to replenish the serum and gummies more than the shampoo and conditioner.
As far as results go, I have noticed my hair line seems to have improved a little (not as much as other reviews made me hope but it's still great progress) and I have much better volume in my hair now. The general condition of my hair has also improved and giving my scalp a little spa treatment every evening has been easy and appreciated. My one annoyance is that when you get the the last of the serum bottle, it's impossible to use the glass pipette/drop attached to the lid so you have to try and pour it out. Other than that, I absolutely love this product and will be continuing with it for a while to see how much it continues to help.
