How does the keep curl range work within the ocs system?

Regardless of hair type, an initial hair analysis should always be performed before choosing which haircare products to use. If it shows the hair’s protein and moisture is relatively balanced, and you have curly hair, use the keep curl range.

If the hair analysis shows hair is lacking moisture, use the aqua boost mask / if hair is lacking protein, use the ocs power build mask.

Can I use OCS if I follow the curly girl programme?

Absolutely! And, if you like to co-shampoo / i.e. using conditioner to ‘wash’ your hair instead of shampoo / the Keep Curl Conditioner is perfect for the job.

I wash my hair as little as possible, how can I get my curls under control when I wake up each morning?

All curls are different and you have to find what works best for yours, but here are a couple of suggestions.

• Wet your hands and scrunch the water through your curls. This will help to ‘reactivate’ the curl memory products already in the hair.

• Tilt your head then lightly spray and scrunch the Keep Curl Memory Spray throughout.
