Liss Therapy – For Straightened Hair

Over the past decade, hair smoothing treatments have become increasingly popular in professional salons.

The smoothing process is complex and lengthy. Its primary purpose is to weaken the sulfur bonds inside the hair shaft. Once these bonds are softened, heat (from a straightener or blow dryer) is applied to reshape them into a smooth, straight alignment. The final step is to rebalance the hair’s pH level, locking the sulfur bonds into their new, sleek structure.

One of the biggest challenges is that these bonds tend to revert to their natural state within days or months. To preserve the results, Bolly J’on Liss Therapy was developed. Its precisely engineered Plex complex reinforces the hair’s internal bonds, preventing them from reverting to their original curly structure. At the same time, plant stem cells help balance the scalp and keep the cuticle tightly sealed, minimizing moisture penetration — a key factor that accelerates bond reversion.

Regular use of the three-step Liss Therapy system helps maintain smoothing results over time, leaving the hair soft, shiny, and full of natural movement.
