Beyond the bottle
Hair health starts from within
Root Rx works on the outside. But if your body is missing what it needs, no topical oil can fill that gap. Here's what to know.
Shedding, thinning, slow growth — these aren't always signs that you need a better product. Sometimes they're your body asking for something it isn't getting. Nutrient deficiencies are one of the most overlooked causes of hair loss, and they're more common than most people realize. Root Rx was formulated to nourish your scalp and strands from the outside. But real, lasting results come when what you're putting on your hair is matched by what you're putting in your body.
Iron deficiency is one of the leading causes of hair shedding, especially in women. Your follicles need oxygen-rich blood to produce hair. When iron is low, your body prioritizes vital organs — and hair growth slows or stops. Low ferritin (stored iron) can cause shedding even when your hemoglobin looks normal. A full iron panel, not just a standard CBC, is worth asking for.
Vitamin D receptors are found directly in hair follicles. Low levels are strongly linked to alopecia and diffuse thinning. Most people are deficient without knowing it — especially those who spend limited time in direct sunlight or have darker skin tones. A simple blood test can tell you where you stand.
Biotin is involved in the production of keratin — the protein hair is made of. True biotin deficiency is rare, but it does cause hair thinning and loss. Most people get enough through diet, but those with certain gut conditions, or who consume raw egg whites regularly, may be at risk. High-dose biotin supplements can also interfere with thyroid lab results — worth mentioning to your doctor.
Zinc plays a role in hair tissue growth and repair, and helps keep the oil glands around follicles working properly. Deficiency can cause hair loss and a dry, flaky scalp. It's also easy to become deficient if you're vegetarian or vegan, since plant-based zinc is less bioavailable than zinc from animal sources.
Hair is almost entirely made of protein. If you're not eating enough, your body will redirect protein to critical functions and deprioritize hair growth. This is especially common during periods of rapid weight loss, restrictive dieting, or high physical stress. The result is often diffuse shedding that shows up 2–3 months after the deficiency begins.
Omega-3s nourish the scalp from the inside the same way Root Rx nourishes it from the outside. They reduce inflammation, support the scalp's moisture barrier, and are associated with increased hair density. Deficiency often shows up as a dry, itchy scalp before hair loss becomes visible.
B12 is essential for producing red blood cells, which carry oxygen to the scalp and follicles. Deficiency is particularly common in people who follow plant-based diets, since B12 is found almost exclusively in animal products. Low B12 can cause fatigue, neurological symptoms, and hair thinning — often all at once.
Magnesium is involved in hundreds of enzymatic reactions, including those that support protein synthesis and follicle health. It also helps regulate cortisol — and chronic stress is a well-documented trigger for hair shedding. Most people don't get enough magnesium through diet alone.
This isn't medical advice.
Root Rx is a hair oil, not a supplement, and we're not doctors. If you're experiencing significant shedding or thinning, a blood panel from your physician is the most useful first step. What we can tell you is that the best results we've seen come from people who are taking care of themselves inside and out — consistently, over time.
Root Rx does its part. You do yours.
Apply it consistently. Eat well. Get your levels checked. Give it time. That's the whole formula.
