Bosley Professional Strength is a clinically developed haircare brand dedicated to the prevention of thinning and the promotion of healthier, fuller-looking hair. Originally developed alongside Bosley Medical — a leading hair restoration clinic — the brand brings a medical-grade philosophy to professional haircare, with formulas that are stronger and more targeted than most consumer thinning hair products.

The core Bosley range is divided into two collections: BosRevive for noticeably thinning, colour-treated hair, and BosDefense for hair that hasn't been treated with colour. Both lines use a blend of botanical actives, amino acids, and scalp stimulants to energize the hair follicle, reduce breakage, and improve overall hair density over time.

At ProHair.ca, Bosley is our primary recommendation for clients experiencing noticeably thinning or fine hair. The system works best as a complete regimen — shampoo, conditioner, treatment, and scalp revitalizer — for cumulative results.
