Scalp massage in a bottle

I was looking for a new good deep cleaning shampoo and seen this. Decided to gamble with a “none salon brand” also since it was what I grew up using (the brand). I had it as my back up shampoo at my dads, and really enjoyed the feeling it tingles in a good way your scalp.
I had to buy a few more (2 in 1) for my dad because he was constantly using it (fun story: he needed shampoo because dandruff and picked it up, it put it on his scalp and started tingling - he thought it was hair removal so he washes it off quick then read the bottle, started using it near every shower on his scalp, face, body turning off the water and enjoying the massage like feeling.
I use it when my hair needs a little “massage” and it doesn’t disappoint. It also doesn’t weigh your hair down which is FABULOUS!
