Some customers of the Sunday Shampoo advised potential poo-ers that it either dried out their hair or didn’t deeply cleanse oily hair as advertised.

Finally, I also get the sense that this product is actually benefiting my hair over time, not just providing an aesthetic glow-up. My GHD straightener also minimizes heat damage, but my hair felt substantially softer and more hydrated post-styling when adding this to my routine, which is rare. And now the juicy stuff: this Bumble and bumble shampoo will take a metaphorical whiff of not only shampoos but also styling products.

On the smash hit product Hairdresser’s Invisible Oil Heat/UV Protective Primer, customers said it was “an absolute must” for frizzy, damaged, tangly hair because it leaves you “ super soft,” smelling delightful, “ so shiny” and with a successfully detangled mane. Uses: A leave-in treatment that conditions and silkens dry, coarse, or brittle hair while providing UV and heat protection.
