FAQ

What helps hair growth?

Hair growth is supported by a healthy scalp and strong hair fibers. Good hair care products that stimulate the scalp and strengthen the hair, such as Long & Strong Leave-in, stimulate and promote hair growth.

How do you stimulate new hair growth?

New hair growth is stimulated by gently massaging the scalp and using products that nourish and strengthen the hair roots. Long & Strong Leave-in promotes hair growth and contains ingredients such as biotin, panthenol, and Centella Asiatica extract, which stimulate the scalp and strengthen the hair fibers. Test results show that with regular use, this contributes to visibly fuller-looking hair.

Does the leave-in conditioner help with hair growth?

The Long & Strong Leave-in stimulates the scalp and strengthens the hair fibers, contributing to visibly fuller and healthier hair.

What does the leave-in do for your hair?

The Long & Strong Leave-in conditioner nourishes, hydrates, and protects the hair. It strengthens the hair fibers, makes hair easier to style, and provides volume and strength, from roots to ends.

How often should I use a leave-in?

Apply the Long & Strong Leave-in to clean, towel-dried hair after every wash to stimulate the scalp and strengthen the hair fibers. Do not rinse.

Do I need to rinse out the leave-in treatment?

No, the Long & Strong Leave-in is a leave-in treatment. You apply it to clean, towel-dried hair and can then style it as desired.

Can I use the leave-in conditioner on dry hair?

For best results, apply the leave-in to towel-dried hair after washing. It can optionally be used on dry hair to condition ends or reduce frizz, but the scalp stimulation works best on slightly damp hair.
