L'Oréal made the BEST shampoo ever ,it was in a dark blue bottle,then they re branded it to Men's anti dandruff shampoo and it was in a black bottle with an orange lid.
Then they discontinued it
I emailed them ages ago and they have no plans to rebrand or replace it.
The fuckers 
I bought loads and had a secret hoard that the rest if the family were not allowed to touch but I'm down to my last half a bottle.
Head and Shoulders with argan oil was a good replacement for a bit as was TBS ginger shampoo buyy recently I've been getting flaky/itchy again and I washed my hair this morning with some shampoo from my secret stash and honestly my hair looks and feels fabulous. No flakes, no itch,just nice shiny swishy hair.
I stood in Boots for ages looking at shampoos and have bought some of the Loreal clay stuff but not holding out much hope tbh.
There was also a Boots own make sensitive range with a sensitive scalp lotion as well as shampoo and conditioner,anyone used that?
I could weep, I had a crap scalp for 25 years and L'Oréal was perfect 
Any suggestions?
