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. I have classic wavy hair: fine, dry, damage-prone, and frizzy. It’s very affected by humidity, and I pretty much always have a halo of flyaways encircling my head from May to September.Naturally, hydrating products are a staple in my haircare routine, though I used to avoid anything with the word “oil” in it for fear of weighing down my super-fine strands. Generally speaking, I’m all about amping up my volume and texture after experiencing a bout of telogen effluvium last year.

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.

Both services are open on weekends from 10:00 am to 8:00 pm. But thanks to adulthood, some preliminary research, and a few gateway products (I see you, Crown Affair), I finally warmed up to the idea of using a hair oil. I learned that the right formula would leave my dry hair incredibly soft and hydrated, not stringy and heavy with product. Hero ingredients: Six “feather-light” oils: coconut oil, argania spinosa kernel oil, macadamia integrifolia seed oil, sweet almond oil, grape seed oil, and safflower seed oil.
