I used this product for about 4months as recommended. I saw very little differences. I think it might help people experiencing only seasonal shading. The bottle is also a little weird and very difficult to pour the liquid.  My advice is, use the money and go to a dermatologist to get appropriate treatment. 

the only treatment that I can apply daily, it doesn't make your hair look greasy and sometimes give a bit of more volume

I have used this product and I really like it makes  my hair looks good and strong 

The product (ampoules) came with kind of a button on the bottom so you should press there. Doesn’t come really a lot of product but definitely you don’t have to squeeze the hard part of it. Regarding the product it is too soon to give my opinion as I have been used just one bottle. 

Ampoules are great,my hair starts growing after few weeks,it’s stronger and doesn’t falling like before. I using two months now,also using complete pink range . This helps me a lot. Just minuses for bottle packing,it’s very poor and also very hard to take product out,I have to cut top every time to take product out. But shame because liquid is very good quality and helps as is described
