Pro Longer is the Série Expert sub-range for long hair with thin ends. Daily aggressions are more visible at the ends than at the roots. The ends become thinner and more sensitive, then split and break. The formulas combine Filler-A100 and amino acids. Filler-A100 penetrates the core of the fiber to thicken the ends. The amino acids strengthen the hair strand. The range is designed for longer, thicker, and more beautiful hair.
The range includes shampoo, conditioner, mask, and a 10-in-1 leave-in cream. The shampoo cleanses the lengths and prepares them for treatment. The conditioner and mask repair the lengths. The hair becomes stronger and shinier. The cream is applied without rinsing to the lengths and ends. It keeps frizz under control and protects the hair from heat.
Wash twice: once to cleanse and the second time to prepare the hair. Apply the mask to towel-dried lengths, leave it on for 3–5 minutes, and rinse. Apply the conditioner to the lengths and ends, comb through the hair, and rinse. Finally, warm a small amount of cream in your palms. Apply it to the lengths and ends, then blow-dry or style as usual.
Frequently Asked Questions
Does Pro Longer speed up my hair growth?
It does not promise this. Pro Longer treats the lengths and ends so that they break and split less. This makes it easier to retain your current length.
Cream or mask, if I have little time?
The 10-in-1 cream is applied to towel-dried hair and is not rinsed out. It provides an anti-frizz effect and heat protection. The mask needs 3–5 minutes to work. It is best to use both.
