This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.
The user is using finasteride, HGH, GHK-CU, BPC-157, KPV, biotin/collagen/keratin vitamins, ketoconazole shampoo, and low-dose naltrexone to address hair loss, avoiding minoxidil due to past shedding experiences. Adenosine is discussed as a potential alternative to minoxidil, though it is noted to be expensive and hard to find.
A dermatologist recommended a new supplement containing annurca apple, which reportedly doubles hair density and increases keratin after 60 days, to be used with finasteride. Some users are skeptical, considering it potentially ineffective or a marketing ploy, while others are open to trying it if it proves effective and affordable.
A 24-year-old male experienced hair loss and side effects from oral finasteride and minoxidil, but saw progress with a topical solution of minoxidil and finasteride, alongside dermastamping and vitamin supplements. He uses 2% Nizoral and keratin shampoo for hair care.
Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.
The user experienced hair thickening and reduced shedding using minoxidil, finasteride, and dutasteride, with a switch from finasteride to dutasteride due to ineffectiveness. They also use a saw palmetto shampoo and take vitamin D3 supplements, while considering potential underlying causes like vitamin deficiencies and hard water buildup.
