Is polysorbate an ingredient (in a cosmetic creme or lotion) which could temporarily increase the diameter of thin & regular size hairs? If so, how long would the effect persist after a single application? And assuming no commercial product is available could it be compounded by any pharmacist?
I am asking these questions because years back a commercial lotion, supposedly from Norway which (falsely) claimed to be the solution to baldness incorporated polysorbate (I can’t remember if it was polysorbate 20). An employee of a pharmacy who told me he was using the product stated that he had noticed an apparent increase in hair density over a short period of time which could not be from new hair growth. I did not try this product after reading critical comments. But I wonder if one could safely use polysorbate or for that matter other products to improve the apparent hair density.
Thanks in advance
I have no experience with this approach for using polysorbate (80 or 20 or any number) as a hair regeneration treatment. If it really worked, I would suspect I would know about it. I will, nevertheless, keep an open mind and probe it with some of my colleagues.
