Name Ingredients:
Polysorbate 80 (also known as Tween 80) is a carrier agent and surfactant that some say aids in removing dihydrotestosterone from hair follicles. Polysorbates were first popularized by the Helsinki Formula, a shampoo and conditioner developed by Finnish researcher Dr. Ilona Schreck-Purola.
Key insights:
- While Polysorbate 60 has some reported improvements in hair growth with use, no published or anecdotal data is available for polysorbate 80.
- It is used as a carrier agent due to its emulsifying and solubilizing properties, allowing oils to be dispersed into solutions.
- Polysorbate 80 may cause scalp dryness, so it may not benefit those with dry or sensitive scalps.
