    TLDR Nutraceuticals that promote hair growth do not reduce tamoxifen's effectiveness in breast cancer treatment.
    This study investigated the effects of various nutraceuticals on breast cancer cell lines (MCF7, T47D, BT483) in the presence of estrogen and tamoxifen, a common breast cancer therapy that often causes hair loss. The nutraceuticals tested included Kelp, Astaxanthin, Saw Palmetto, Tocotrienols, Maca, Horsetail, Resveratrol, Curcumin, and Ashwagandha. Results showed that these nutraceuticals did not interfere with tamoxifen's inhibitory action on estrogen-stimulated DNA synthesis; some even enhanced tamoxifen's effects. The study also found that nutraceuticals increased ERβ expression and localized estrogen receptors around the nuclear periphery, suggesting a potential protective effect and a role in promoting hair growth. Further research is needed to confirm these findings and assess the safety and efficacy of using nutraceuticals as an adjuvant therapy for hair loss in breast cancer patients undergoing endocrine therapy.

      community Dutasteride vs Finasteride and Steroid

      Dutasteride is preferred over finasteride for hair loss due to fewer side effects. Combining dutasteride with minoxidil and RU58841 is effective for hair regrowth, even during steroid use.

      A user shared their 9-month progress using RU58841 at 2% daily for hair regrowth, initially starting at 5% but reducing the dose due to early signs of gynecomastia, which has since mostly resolved. They achieved their goal of regrowing hair at the temples and hairline.

      People regret not starting hair loss treatments like Minoxidil and Finasteride earlier, as they've lost significant hair by waiting. Some experienced side effects like itchy nipples or increased libido, but overall, they wish they had acted sooner to prevent hair loss.

      A 20-year-old started taking finasteride for hair loss at 18, saw improvement, but developed erectile dysfunction (ED) after taking accutane. Despite stopping both medications, ED persisted, and hair loss worsened. Advice given includes considering tadalafil for ED, resuming finasteride, using minoxidil, and addressing psychological factors through positive thinking and lifestyle changes.
