If you’re just beginning your journey to combat hair loss caused by weight loss drugs, all the information out there can feel overwhelming. The truth is, while there are countless hair loss treatment products and supplements marketed for hair regrowth, only a handful are widely believed to be effective—and even fewer have robust scientific backing.

What Does the Research Say?

• Minoxidil: Not a DHT blocker, so can treat types of hair loss that aren't related to DHT, such as telogen effluvium. It’s one of the most effective medications available for treating male pattern baldness, especially when it's used in combination with finasteride.

• DHT Blockers: Medications like finasteride and dutasteride reduce DHT levels by up to 60% and 90%, respectively. This suppression prevents hair follicle miniaturization, helping to slow or stop hair loss treatment products in up to 90% of men. Studies also show that around 65% of finasteride users see some level of regrowth. Natural supplements like saw palmetto and green tea extract may also be used for their DHT blocking attributes.

• Spironolactone: Particularly effective for women, spironolactone reduces androgen levels by blocking androgen receptors and lowering DHT production. Studies have shown that it can significantly reduce shedding and improve hair density over time, making it a go-to option for hormonally driven hair loss such as female pattern baldness or hair loss related to conditions like PCOS.

While other hair loss treatment products, like supplements and topical solutions, may offer supportive benefits, these options are best combined with DHT blockers and minoxidil for maximum efficacy. The key to success is consistency.
