1. Wash your hair at least weekly. 

Water is the supreme moisturiser. When you wet your hair the water molecules actually penetrate the hair shaft and make the hair softer and more elastic.

Moisture = hydration, hydration = water, hydrated hair = less breakage.

2. Use a shampoo and conditioner within the same product line or test the pH of your chosen shampoo and conditioner to ensure they complement each other.

Conditioner is meant to be more acidic than shampoo. The lower pH of the final product used in the cleaning process (typically the conditioner) helps to seal off the hair; sealing the hair means hair cuticles are smoothed down and moisture is held in better. A shampoo and conditioner within the same product line will be developed with this requirement in mind.

For example, the shampoo of one brand may have a pH of 4.5 and the conditioner 3.5 meaning that your hair is properly sealed off. But if you then go and use a conditioner of another brand whose pH is 5.0, this sealing off process won’t happen properly.
