Review: Philip Kingsley Density, Thickening Protein Spray

Of all the products we receive, Philip Kingsley’s Thickening Protein Spray is the one I’ve been frantic to try. One glance at my hair tragedy, and you will understand why. A foolhardy combo of chronic haircare laziness, and a slightly worrying obsession with heat styling, has left me with hair so damaged, it needs its own therapist.

Not ready to accept the scissored hand of fate leaves me in quite a predicament. Visualise, if you will, hair strands that break before touching a hairbrush, and locks with less volume than an e-book! Add heat protection spray to the mix, and – oh, dear God, no.

The Reason For Reviewing The Density Protein Spray

So, when Philip Kingsley’s team of expert trichologists created a blazing light of haircare power, I was transfixed. Designed to take straw hair, and spin it into a crowning glory of sheer gold, we (ahem, I) had to test it out.

After a continual wave of mediocre hair products that all fell behind on their promises, this new launch felt like a pot of haircare gold. Philip Kingsley’s Thickening Protein Spray restored not only my hair, but also my faith in hair strengthening formulas.

This multitasking treatment is advanced haircare in action. The combined fortifying hair proteins work like magic. My hair is noticeably stronger and looking healthy again. But does it increase density, adding that much sought-after volume? We think so!

During the first week, I was disappointed that my hair didn’t match up to Jen Aniston’s level of shiny perfection. But I soon realised Philip Kingsley’s product doesn’t cater for head transplants. However, by the end of week two, my hair was becoming shiny. For hair that was so in need, that people were gifting me hats, this is quite a feat.

Concluding Thoughts

There’s no doubt this lightweight formula dramatically hydrates and nourishes the hair. You can see a visible improvement after just one use. Better yet, it doesn’t let you down when you reach for your straighteners. Having a hair product that offers high-level protection is priceless.
