    TLDR Amino acid-complexed trace minerals improve hair quality and activity in senior dogs.
    A 90-day study with 43 senior dogs examined the effects of inorganic versus amino acid-complexed trace minerals on haircoat and activity levels. Dogs were divided into Control, TMC, and TMC-LG groups. Results indicated that TMC and TMC-LG groups experienced increased hair growth, superior hair quality, decreased shedding, and more active hours compared to the Control group. Specifically, TMC-LG dogs had significantly longer hair and higher growth rates, shedding less hair while maintaining activity levels. The study suggests that amino acid-complexed trace minerals can enhance haircoat quality and vitality in senior dogs.

Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

      Grapefruit juice doesn't significantly affect finasteride or dutasteride. Drinking topical minoxidil is risky; saw palmetto is less effective than finasteride or dutasteride for hair loss.

      community I am actually regrowing my hairline without minoxidil or finasteride (mechanical stimulation)

      Regrowing hairline without the use of Minoxidil or Finasteride, and instead using mechanical stimulation such as Derma Roller, Nizoral, Zinc Pyrithione, Scalp Massage, Scalp Exercise, Fish Oil and other topical solutions. It is cautioned that there are risks associated with not using medically-prescribed treatments, but it is suggested to consider mechanical stimulation in addition to those prescribed treatments.
