Frequently Asked Questions
What is the PURC Keratin Treatment?
It is a Brazilian keratin-based formula designed to repair, smooth, and straighten dry, frizzy, or chemically damaged hair.
How does it help my hair?
It replenishes lost keratin, strengthens strands, eliminates frizz, and leaves hair silky smooth with a natural shine.
Does it have any side effects?
Our formaldehyde-free option is the gentlest solution. Stronger concentrations (5%, 8%, 12%) are safe when used correctly but should be applied in a ventilated space due to a strong odor.
What are the ingredients?
Pure keratin combined with a Brazilian chocolate-scented formula. Available in different keratin strengths depending on your hair type and condition.
How often can I use the PURC Keratin Treatment?
One application lasts up to 3 months. It is not necessary to use it more frequently unless hair regrowth or texture requires reapplication.
What are the directions for use?
Wash hair with PURC Purifying Shampoo (2–3 times depending on condition).
Blow-dry completely.
Apply keratin treatment section by section, combing through.
Leave on for 20–30 minutes depending on hair type.
Blow-dry again and seal with a flat iron at 430–450°F (7–10 passes per section).
After 72 hours, wash with PURC Daily Shampoo (sodium chloride-free).
How long before I see results?
Results are visible immediately after the treatment—hair becomes smoother, straighter, and shinier.
Are there any precautions?
Yes. Use in a well-ventilated area or wear a mask due to the strong odor. Avoid using the formaldehyde-free version on golden/blonde hair to prevent color change. If hair length exceeds 17 inches, 2 sets are recommended.
What size does the PURC Keratin Treatment come in?
Each pack contains one 100ml bottle of the PURC Brazilian Keratin Treatment, which is suitable for a single full application. For longer hair (over 17 inches), we recommend using two sets to ensure complete coverage and best results.
