How to Use Leave In Hair Treatments

Leave in hair treatments are the secret to healthier and more manageable hair. They continue working long after you have stepped out of the shower to repair, protect and enhance your style. The key is choosing the right formula for your hair type. Unlike traditional treatments, the ghd rehab range of leave in treatments is heat activated, meaning it not only protects your hair during styling but also strengthens, smooths and adds shine as you use your ghd hair styling tools.

Why do heat-activated leave-in hair treatments work better?

They work better because heat helps the treatment bond to your hair, giving instant and longer lasting results.

When learning how to use leave in hair treatments, it is important to know that hair cuticles are more open when damp, allowing the formula to penetrate deeply. As you style with heat from your ghd tool, the active ingredients attach to the hair fibre and lock in smoothness, strength and shine. This makes ghd rehab treatments more effective than traditional leave ins, as the results are activated and enhanced while you style your hair.

FAQs on How to Use Leave In Hair Treatments

Q: How long do you leave hair treatment in?

A: Leave in treatments stay in your hair with no need to rinse. With ghd rehab, benefits are activated immediately during styling and last until your next wash.

A: Apply to clean, towel dried hair. Damp hair helps the formula absorb and allows ghd rehab to activate with heat.

Q: Do I still need conditioner if I use a leave in treatment?

A: Yes. Conditioner smooths and detangles, while leave ins provide ongoing repair and protection. They work best together.

A: ghd rehab treatments are designed to be heat activated, not overnight masks. For best results, apply to damp hair and style with heat to lock in benefits.
