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.

Frequently Asked Questions
Is Bosley the same as Bosley Medical?
Bosley Professional Strength is the haircare product line developed alongside Bosley Medical, the hair restoration clinic. The products use similar philosophy but are not medical treatments — they are professional-grade haircare products.
How long does Bosley take to show results?
Most users notice reduced shedding within 2–4 weeks and improved hair thickness within 2–3 months of consistent use. Results vary by individual and severity of thinning.
What is the difference between BosRevive and BosDefense?
BosRevive is formulated for colour-treated hair and is safe for chemically processed strands. BosDefense is for non-colour-treated hair and contains a higher concentration of actives suited to natural hair.
Can women use Bosley?
Yes. Bosley is formulated for both men and women experiencing thinning. Both BosRevive and BosDefense are suitable for female pattern thinning.
Should I use the complete Bosley system?
Yes. Bosley is designed as a complete regimen — shampoo, conditioner, and scalp treatment — for best results. Using the full system delivers more cumulative benefit than individual products alone.
Is Bosley safe for daily use?
