Dr. Lara Devgan on the Future of Hair Growth: A Four-Step Scientific Approach
Hair loss can feel like a losing battle—but according to Dr. Lara Devgan, board-certified plastic surgeon and founder of Dr. Lara Devgan Scientific Beauty, science is giving us real tools to turn the tide.
When asked if she sees science progressing hair growth, Dr. Devgan outlines a clear four-step “algorithm” that combines medical insight, biotech advances, and clinical treatments. Each step builds on the one before it, offering a personalized, scientific pathway to fuller, healthier hair:
Address Vitamin Deficiencies & Medical Comorbidities
Hair health starts from within. “You can’t fix hair growth without first correcting what’s going wrong inside the body,” says Dr. Devgan. She begins by checking for nutritional gaps (like iron, biotin, vitamin D), thyroid imbalances, and autoimmune conditions. Without this foundation, no topical or procedural treatment will be truly effective.Oral and Topical Minoxidil
One of the most studied and effective treatments, minoxidil increases blood flow to hair follicles and extends the growth phase. “We’re using both oral and topical formulations now to target hair thinning from multiple angles,” she explains. Personalized dosing makes this more effective and better tolerated than ever before.Platelet-Rich Plasma (PRP)
PRP therapy takes your own blood, concentrates the growth factors, and re-injects them into the scalp to stimulate dormant follicles. “Think of it as biohacking your body’s healing system for hair regeneration,” says Dr. Devgan. It’s especially useful in early to moderate stages of hair loss.Hair Transplantation
For patients with more advanced hair loss or those who’ve exhausted other options, surgical transplantation offers permanent, natural-looking results. “It’s the final step in the algorithm—when you’ve done everything else right and still need density,” she says.
From internal health to surgical precision, Dr. Devgan’s four-step approach reflects how science is elevating the art of hair restoration—making the future of hair growth not just hopeful, but achievable.
