Q. What is a leave-in hair treatment?
A leave-in hair treatment is a no-rinse product that stays in your hair after washing. Unlike rinse-out masks or conditioners, it’s applied to damp or dry hair and left in to deeply nourish, repair, protect, and strengthen strands throughout the day. These treatments address concerns like breakage, frizz, heat damage, and dullness – making them a key step in any effective haircare routine.
Q. How often should I use a leave-in hair treatment?
You can use most leave-in hair treatments every time you wash your hair. For best results, apply them to towel-dried hair before heat styling or air drying. If your hair is dry, damaged, or colour-treated, using a leave-in treatment two to three times a week – or even daily – can help maintain strength, softness, and manageability.
Q. Should I wash out my leave-in hair treatment?
No – leave-in treatments are meant to stay in your hair to provide ongoing benefits. There’s no need to rinse them out. Just apply as directed (typically to damp hair), then style as usual. Washing the treatment out too soon will limit its effectiveness.
