How long does keratin last, and how do you make it last longer?

Two options, two timelines

• Keratin Express Blowout: the quicker, shorter-term smoothing service.
• Keratin Complex: the longer-lasting treatment for serious frizz.

How long either lasts depends on your hair's texture and porosity, how often you wash, and your aftercare. Your stylist will set expectations for your hair at your appointment.

What shortens results

• Sulfate shampoos and clarifying products
• Very frequent washing
• Chlorine and salt water without protection
• Skipping the aftercare window your stylist gives you

Aftercare that works

1. Follow the specific wash and styling instructions for your treatment.
2. Switch to sulfate-free shampoo and conditioner.
3. Wet your hair and apply conditioner before swimming.
4. Stretch time between washes with dry shampoo.
5. Sleep on silk or satin to reduce friction.

Keratin and color

You can do both. Ask your stylist how best to schedule them.
