Who it’s for

Fragile, damaged or over-processed hair. Hair that snaps, feels rough at the ends, or has lost its stretch. Because it’s lightweight, it suits fine hair that can’t take a heavy mask.

What to know

  • Strengthening, not smoothing. It improves condition; it won’t change frizz or texture.
  • If your scalp is part of the problem as well as your hair, book Liquid Scalp + Hair instead.

    “Absolutely lovely. I have very damaged abused hair from years of bleaching and extensions. They were kind, polite and non-judgmental towards my hair concerns. They are are real miracle workers. My hair has gone from a damaged birds nest to a beautiful, well conditioned sleek professional cut. I really couldn’t be happier. Thank you so much.”

    “I had a wonderful experience getting a blow-dry but also while I was there I got a detox scalp treatment that's worked wonderful on my scalp. Oli was so kind, caring and knowledgeable. I felt very comfortable with them and at the salon.”

    “My experience with Peter James Scalp and Hair Clinic has been truly life-changing, and I do not say that lightly.When I first walked through their doors, I was in a very vulnerable place. My hair and scalp had been severely damaged by poorly fitted extensions, leaving me not only in physical discomfort but emotionally distressed. The damage was so extreme that I had resorted to wearing partial wigs to hide what had happened. I felt embarrassed, defeated, and completely stripped of my confidence. My hair had always been part of my identity, and I genuinely feared I might lose it — along with a part of myself.From the very first consultation, James treated me with such kindness, patience, and understanding. He truly listened — not just to the practical concerns about my hair and scalp, but to the emotional toll it had taken on me. There was no judgement, only reassurance and a clear, knowledgeable plan forward. Alongside Peter, they carefully and thoughtfully began the process of restoring my hair’s health.The transformation has been nothing short of remarkable. Through their expert product recommendations, gentle treatments, and meticulous hands-on care, my scalp has healed and my hair has been brought back to life. But what they restored goes far beyond hair. They gave me back my confidence, my dignity, and my sense of self.What makes this clinic so special is not only their exceptional expertise, but their compassion. Every appointment feels unhurried and personal. The salon itself is a calm, welcoming sanctuary — a place where you feel safe and cared for. The entire team are warm, professional, and genuinely invested in their clients’ wellbeing.Without their delicate care, ongoing support, and honest guidance, I truly believe my outcome could have been very different. I am beyond grateful for the rescue they provided during one of the most difficult periods of my life.I cannot recommend them highly enough. If I could give 10 stars, I absolutely would. Thank you, from the bottom of my heart, for everything you have done for me. I am, without question, a lifelong client.”

    “I absolutely love this salon! The atmosphere is so calm, relaxing, and never nerve-wracking like some places can be. James & Peter are genuinely delightful and you can tell they truly care about the health of your hair, not just the end result. Every visit feels comfortable and professional and is SUCH a vibe. I came in with fried damaged blonde hair and James has totally transformed it back to healthy hair. If you’re looking for a new salon and aren’t sure where to go, this is definitely the place to try, you won’t be disappointed!💓💓”

Decent prices (you’re given options for extra treatments but never pressured), great atmosphere and super friendly team. I appreciate that the appointments are never rushed, always feels like genuine pampering!”

Frequently asked questions

What does Liquid Hair actually do?

It's a lightweight reconstructive treatment that infuses the hair with amino acids and keratin building blocks, rebuilding its structure from the inside rather than coating it on the outside.

How do I know if my hair needs it?

It's for fragile, damaged or over-processed hair: hair that snaps, feels rough at the ends, or has lost its stretch.

My hair is fine. Will it weigh it down?

Liquid Hair is lightweight, which is why it suits fine hair that can't take a heavy mask.

Will it get rid of frizz?

No. It's strengthening, not smoothing: it improves condition, but it won't change frizz or texture. If frizz and long-term manageability are what you're after, Smooth Filler is the service for that.

Should I book Liquid Hair or Liquid Scalp + Hair?

Liquid Scalp + Hair is this same reconstructive treatment plus a scalp treatment. If your scalp is part of the problem as well as your hair, book that instead.
