I wasn’t going to let my freshly washed hair be ridden with germs from the Tube, so I went to the salon downstairs for a blow-dry, which is an add-on. Overall, my hair was noticeably shinier (tick), but it always is when I use heat to dry it instead of my usual air-drying routine. However, the real results could be seen when it came to the next wash day scheduled in my calendar and my roots weren’t remotely greasy. A massive feat.

If you are suffering from hair loss or severe seborrheic dermatitis, I would always visit a trichologist – a head spa isn’t going to cut it. But if you’re simply looking for a guaranteed good hair day, a deep cleanse for a refresh and a relaxing 90 minutes, this is the way to go. Plus, those kinks in your neck and shoulders will benefit too. It’s an elite upgrade on a traditional wash and blowdry.
