Weather-Tested Beauty Built for Wind, Salt, and Sea.
Named after the wind-swept, salt-sprayed shores of Cornwall, Three Mile was born to defend skin against the elements. We create high-performance, barrier-restoring skincare designed to nourish, seal, and protect—wherever your trail takes you.
Made with care and unconditionally loved by our customers, this signature bestseller exceeds all expectations.
Restore compromised strands to their former resilience with this intensive keratin treatment. A luxuriously rich mask that melts into hair, this formulation works to mend structural damage whilst imparting a luminous, touchable softness that lingers long after application.
Deep Restoration: Hydrolyzed Keratin and Wheat Proteins reinforce the hair's internal matrix, visibly reducing breakage and split ends whilst restoring elasticity and movement.
Sensory Indulgence: Shea Butter and a Biomineral Complex create a velvety texture that absorbs seamlessly, leaving strands supple and manageable without heaviness or residue.
Antioxidant Nourishment: Vitamin E and peptides work synergistically to protect against environmental stressors whilst infusing hair with sustained hydration and a refined, healthy lustre.
Apply the mask generously to clean, damp hair, concentrating on mid-lengths and ends. Allow 5–10 minutes for the formulation to penetrate, then rinse thoroughly. Incorporate into your weekly ritual for visibly transformed, resilient hair.
