Review (1/5): Would not recommend
The product directions say to use just a cap full, but this bottle comes with a flip top, not a cap. If I use just a cap full, like from a olive oil bottle or other such product, it would not be enough to distribute through my scalp, let alone be enough to thoroughly wash my hair. The shampoo doesn't lather much so it makes it even more challenging to figure out how to get my hair clean. The shampoo also makes my skin red and blotchy. I tried to be very careful to not let it touch the rest of my skin, but even with the best of my intentions, it does still cause redness on my skin. The redness goes away, but it is worrisome to me that it is causing such a reaction. I use a number of other Sebamed products which I gladly recommend, but unfortunately I can't recommend this particular one. I haven't noticed any improvement in my thinning hair and I am concerned about the redness it causes my skin.
