Biological Observations from Feeding Heated Corn Oil and Heated Peanut Oil to Rats

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

The conversation discusses the safety study of PP405, emphasizing that early trials focus on safety rather than efficacy, and that any efficacy data from such a short study should be viewed skeptically. It also highlights that the information released is primarily for securing funding, and that meaningful efficacy results are expected in later phases.

Peppermint oil and olive oil are being used to potentially improve hair growth, with some initial observations of stronger, thicker hair. Another user is using a mix of peppermint, coconut, castor, and rosemary oils, noting healthier and softer hair but no significant regrowth yet.

A user experimented with applying pure rosemary oil to a single hair strand twice daily, observing increased thickness and pigmentation, but questioned if the oil or the application method caused the change. Some users noted rosemary oil might be as effective as 2% minoxidil for hair growth, though others warned about potential harm from using undiluted oil.

Oral castor oil is discussed for hair and eyebrow thickening, with some users reporting positive results at 1 mL per day, but others experiencing laxative effects. It is cautioned against for pregnant women due to potential risks, and there is skepticism about its effectiveness for hair growth.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.
