Sunsilk Black - Dangerous High Caustic. Review on Sunsilk Shampoo

My hair are voluminous and I generally keep long hairs. Since last six months I started using sunsilk black shampoo to get my hair silky and shining, seeing an advertisement in TV. It done well in the beginning and I was very happy too seeing its good effect. But I after use of about six months I realize that my hair are being lesser dense that earlier. I noticed that my hairs a falling very fast. It was only due to this caustic shampoo. Now I understood that it works fast due to high level of caustic in this shampoo. This caustic component is main enemy of the roots of the hairs and cut the hairs from the root. Now, it is evident for me that this shampoo can give temporary shining to hairs but not life to it. It will kill your whole hair untimely. Now, I have completely stopped using this shampoo and advice all not to use this caustic shampoo.
