Can you apply oil on head after permanent hair straightening?

It's generally recommended to avoid applying oil on your hair immediately after permanent hair straightening. The chemicals used in the straightening process can make hair more susceptible to damage, and oil may weigh it down or interfere with the treatment's effectiveness. It's best to wait at least a week before using oil or any heavy products, allowing the hair to fully settle into its new texture. Always consult your stylist for personalized advice based on your hair type and treatment.
