7 Root-Cause Hair Loss Supplements for South Africans in 2025 – By Dr Olz

Hair loss is often the first visible sign of something deeper: hormonal imbalances, nutrient deficiencies, chronic stress, thyroid dysfunction, or even gut malabsorption. As Dr Olz, I don’t treat symptoms—I correct the root cause. And that’s the only way hair truly regrows.

Here are 7 supplements I recommend in 2025 to restore hair strength, reduce shedding, and nourish follicles from the inside out—available across South Africa on AskDrOlz.com.

1. MetaCollagen Pro+ – Collagen for Hair Structure & Scalp Elasticity

Why it works:
Hair is 95% keratin, and keratin production depends on collagen availability. MetaCollagen Pro+ provides Type 1 collagen, the foundational building block that strengthens the hair shaft, improves scalp integrity, and reduces breakage.

✅ Best for: Structural hair loss, postnatal thinning, aging scalp
💊 Dosage: 1 scoop daily

---

2. Zinc Glycinate – DHT Blocker & Follicle Repair

Why it works:
Zinc helps regulate DHT (dihydrotestosterone), a hormone that miniaturises hair follicles—especially in androgenic alopecia (common in women with PCOS or men with receding hairlines). Zinc also supports wound healing of the scalp.

✅ Best for: Hormonal hair loss, oily scalp, acne-related shedding
💊 Dosage: 1 tablet daily

---

3. Vitamin D3 1000 – Hair Cycle Activation & Autoimmune Regulation

Why it works:
Low vitamin D is linked to telogen effluvium and alopecia areata. D3 helps regulate immune activity around the follicle and supports a healthy hair cycle.

✅ Best for: Autoimmune hair loss, seasonal shedding, fatigue-related hair loss
💊 Dosage: 1 tablet daily

---

4. Thyrosol® – Thyroid Support for Hair Regrowth & Energy

Why it works:
Hair loss can be the earliest sign of thyroid dysfunction—even when TSH is “normal.” Thyrosol® supports thyroid hormone production, conversion (T4 to T3), and adrenal resilience. I recommend this for patients with slow metabolism, dry hair, and chronic fatigue.

✅ Best for: Thyroid-related hair thinning, cold intolerance, fatigue
💊 Dosage: 1 capsule, 3 times daily with meals

---

5. Ultra Potent-C® 1000 – Collagen Co-Factor & Antioxidant Scalp Repair

Why it works:
Without vitamin C, your body can’t produce collagen. Ultra Potent-C also improves microcirculation to the scalp, helping deliver oxygen and nutrients to the follicle bed—especially important for post-inflammatory hair loss.

✅ Best for: Brittle hair, poor wound healing, iron absorption support
💊 Dosage: 1 tablet daily

---

6. Biotin 5000 mcg – Keratin Production & Hair Strength

Why it works:
Biotin is a B-vitamin essential for keratin production. Deficiency often leads to hair thinning, brittle nails, and dull skin. In my practice, I use 5000 mcg (5 mg) for clients with brittle hair and nails or post-antibiotic hair loss.

✅ Best for: Biotin-deficiency related shedding, hair brittleness
💊 Dosage: 1 softgel daily (ensure it’s high-dose, 5000 mcg)

---

7. Iron Bisglycinate – For Telogen Effluvium and Female Hair Loss

Why it works:
Low iron is one of the most overlooked causes of hair loss in women. Even if ferritin is “normal,” levels below 70 ng/mL can impair follicle growth. Iron Bisglycinate is a gentle, highly absorbable form that doesn’t cause constipation.

✅ Best for: Heavy periods, postpartum women, fatigue with hair loss
💊 Dosage: 1 capsule daily (test ferritin before use)

Hair Loss Is a Symptom – Not a Standalone Diagnosis

As Dr Olz, I remind my patients that hair regrowth takes time—usually 3–6 months, and only happens when you correct the root cause:

• Thyroid dysfunction? Use Thyrosol®
• Nutrient deficiency? Correct it with collagen, zinc, vitamin D, or iron
• Hormonal imbalance? Focus on DHT regulation and stress support
• Structural weakness? Support the follicle matrix with collagen + biotin
