Hard water has become a household problem these days and it is very difficult to avoid using it especially while bathing, however the impacts of it cant be avoided. The direct impact on my body was on my hair. I took me nearly 6 months to realise that density of my hair is reducing.
I started using it and honestly it took me 2 months to see the results(on bottle its written 3 weeks). While density is still not increasing at the rate which is expected but yes quality of hair has definitely improved which includes:
Less hairfall now
Shinier hair
Only Drawback: Fragrance. My roommates sometimes make fun of it but I guess its acceptable if end results are achieved.
