After undergoing a hair smoothening treatment, it’s essential to give your hair time to adjust to its new state before applying natural oils.
The formaldehyde in the treatment needs time to work effectively, and applying oil can interfere with this process, potentially causing excess frizz and damaging the hair’s natural shine and texture.
Therefore, it’s recommended to wait for about 4 weeks before using oils on your hair after smoothening. During this period, focus on gentle shampooing and conditioning to maintain your hair’s health.
Once the waiting period is over, you can resume using natural oils to nourish your hair and help it regain its strength and shine.
