The science

Panthenol's main job in products is to moisturise. It’s a humectant, meaning that it can help to attract water and then hold onto it. It can also help our skin to produce more lipids that are important for a strong and healthy skin barrier. 

Another great thing about panthenol is that it has anti-inflammatory and skin protecting abilities and it can also reduce irritation.

Panthenol can reduce the appearance of thinning hair and this, along with boosting the volume of hair, results in the hair looking more healthy.

TLDR 

Panthenol is a great moisturizer which helps in detangling, softening and smoothening the hair, along with preventing hair thinning and boosting volume.
