Activation of the Human Transient Receptor Potential Vanilloid Subtype 1 by Essential Oils

Mustard oil mixed with rosemary, peppermint, and lavender essential oils is used for hair volume and growth, with microneedling as an additional treatment. Mustard oil is preferred over other oils for a fuller hair appearance.

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.

Rosemary oil can smell like camphor and is considered okay for hair use. The user bought a large bottle from a wholesaler to save costs.

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.

The conversation discusses using Dr. Bronner's unscented soap as a potential shampoo and the benefits of adding rosemary oil. One user suggests applying rosemary oil to the scalp before washing.

Rosemary extract showed high inhibitory activity against DHT, similar to finasteride and dutasteride, but the conversation includes skepticism about its effectiveness in humans since the study was done on mice and rosemary oil is often considered ineffective based on personal experiences. Some suggest trying rosemary oil alongside other treatments, while others emphasize the difference between the extract used in the study and the oil.
