It's a coal tar based shampoo by Neutrogena. It doesn't smell the best, but it helps with the itchies and flakeyness. My mate and I use it pretty regularly (at least in his hair).

Mine are almost 3 years, so I do believe it would be fine! I broke out in hives when I used the baking soda the 1st time, then it took me 2 years to actually try it again now it is all I use! I really want to try the acv rinse though, T- Gel sounds bomb too, is that good for your dreads though? How did you use the acv rinse Faelwynn, thanks in advance!!
