Two sprays. No rinse. Hair that's stronger, smoother, and easier to work with.
Most men skip the step between washing and styling. They towel dry, maybe add product, and leave. But wet hair is at its most vulnerable the cuticle is open, the shaft is swollen, and every pull from a comb causes structural damage that accumulates over time.
The Keratin Leave-In Hair Mist closes that gap. Two sprays onto towel-dried hair deliver a weightless layer of hydrolysed keratin that strengthens each strand and smooths the cuticle, so hair combs through cleanly instead of snagging. Furcellaria a Baltic red algae extract forms a light film that reduces frizz and adds a natural lustre without weight.
The step most men don't know exists. The one that makes everything after it styling, holding, looking right at 6pm actually work.

Key Ingredients
Hydrolysed Keratin
Fills micro-damage in each strand for immediate strengthening. Adds natural shine by smoothing the cuticle, so the surface reflects light instead of scattering it.
Furcellaria Lumbricalis Extract
Baltic red algae extract that forms a protective film around each strand. Smooths the cuticle, reduces frizz, and adds a natural lustre without weight.
Lactic Acid
Keeps the formula at hair's natural slightly acidic pH, which helps the cuticle lie flat rather than lifting and roughening.
Citrus & Geranium Oils
Natural essential oils that give the mist its clean, fresh scent without the synthetic fragrance load most leave-in products carry.

Questions
What does this actually do?
Three things. It strengthens each strand with keratin, smooths the cuticle so hair combs through without snagging, and adds shine. The practical result is less breakage when you comb wet hair, and hair that looks less dull.
Will this make my hair stiff or crunchy?
No, the mist is weightless. It absorbs into the hair rather than coating the surface. No crunch, no stiffness, no visible residue. Your hair moves naturally.
Can I use this with styling products?
Yes, apply the mist first as a base layer, then style as normal. The keratin gives styling products a smoother foundation to work with, and your style holds better because each strand is stronger.
How long does one bottle last?
At 2–3 sprays per use, the 100ml bottle lasts approximately 12+ weeks nearly 3 months. One of the longest-lasting products in the Reign range.
