Why Treating Hair Loss Requires More Than One Solution

The way I think about hair loss is in layers

The Internal Drivers of Hair Loss

Hair follicles are incredibly sensitive to what's happening inside the body. Hair growth isn't always prioritized when nutrients and energy are needed elsewhere. Some of the most common drivers include hormone shifts, thyroid dysfunction, iron deficiency, insulin resistance, chronic stress and elevated cortisol, autoimmune activity, and nutrient deficiencies.

When any of these systems are out of balance, the follicle gets the signal that growth isn't a priority — the hair cycle shifts toward shedding to save resources.

Understanding the Hair Growth Cycle

Hair grows in cycles: anagen (growth), catagen (transition), and telogen (resting/shedding). Many hair loss treatments work by helping follicles stay in the growth phase longer, or by stimulating follicles that have gone dormant. But if the internal issue isn't addressed, these treatments often have limited success — it doesn't mean they don't work, just that they work in certain circumstances.

Conventional Medical Treatments

Dermatology has developed several tools that focus directly on the follicle. Minoxidil works by increasing blood flow and extending the growth phase, but doesn't address hormones or DHT. Some physicians prescribe medications that block DHT — the hormone responsible for follicle miniaturization in androgen-driven hair loss — including finasteride, dutasteride, and spironolactone.

These can be effective for androgen-related hair loss, but they target one mechanism and don't address other contributors like autoimmune conditions, nutrient deficiencies, thyroid imbalances, or inflammation. For many people, they can slow or stabilize hair loss — but not without trade-offs. These drugs can also lower testosterone, which may mean less energy, reduced ability to build muscle, lower libido, and even erectile dysfunction.

In-Office Treatments That Stimulate Growth

Several clinical treatments have emerged to stimulate follicle activity directly.

PRP (platelet-rich plasma) uses the body's own growth factors to stimulate follicle repair and reduce shedding — a small blood sample is drawn, processed to concentrate the platelets, and delivered back into the scalp, either through direct injection or combined with microneedling.

One device I like for microneedling is Exion, an RF system designed to stimulate collagen and follicle activity with fewer passes and less needle depth — meaning less discomfort and minimal downtime.

These therapies work best when paired with approaches that address the internal drivers too.

Red light therapy is another option — it increases mitochondrial activity and circulation, helping follicles get the energy they need to grow, and can be done at home. I like the iRESTORE red light cap.

The Often-Overlooked Piece: Scalp Health

Healthy hair grows from a healthy scalp. An inflamed scalp can't produce or grow the best version of hair. The scalp is living tissue that needs circulation, oxygen delivery, balanced oil production, a stable microbiome, and low inflammation.

Modern hair serums often include peptides, caffeine, and anti-inflammatory compounds to support these conditions — You can find my comprehensive article on products I recommend here.

Supplements and Nutrient Foundations

Supplementation works best when it's targeted to correct an actual deficiency. Biotin, despite its popularity in hair products, typically only benefits hair growth in people with a true deficiency — which is relatively rare. Nutrients that matter most for hair growth include iron, zinc, adequate protein, vitamin D, glycine, and MSM.

Without these building blocks, the body can't produce strong hair fibers. Figuring out why these nutrients are low often starts with looking at gut health alongside testing nutrient levels.

Our understanding of hair biology has advanced tremendously over the past decade, bringing more options that actually work. The most effective approach is rarely a single product or treatment — real progress usually comes from addressing internal health, scalp environment, and follicle stimulation together.

When those pieces come together, many people begin to see meaningful improvement.
