2. Olaplex No. 5 Bond Maintenance Conditioner

We'll do whatever we can to protect our hair from split ends, and this moisturizing conditioner promises to do just that. Not only will it relink broken bonds, but it'll also strengthen your locks to prevent breakage down the road.

3. Olaplex No. 3 Hair Perfector

Add this to your damp, post-shower hair to repair broken bonds and restore its natural shine and health. If your hair is in good shape, use it once a week from your roots to your ends. If you have some damage, use it up to three times a week. It's a ten-minute commitment that makes a big difference in terms of minimizing flyaways.

4. Olaplex No. 6 Bond Smoother

Trade your leave-in conditioner for this reparative styling cream that hydrates, protects and strengthens in one fell swoop. Use it before blowdrying to reduce flyaways and frizz and to speed up the drying process overall.

While some oils simply smooth and add shine to your hair, this bonding oil provides UV and heat protection (up to 450 degrees  Fahrenheit). It's ideal for people who use flat irons or curling irons on the daily, and it can be used with all hair types.
