Vitamin C vs Vitamin E for Hair Growth: Benefits, Side Effects & Usage Guide
BY TRYBELLO
Sep 09, 2025
Key Takeaways
- Vitamin C strengthens hair from within by boosting collagen, improving iron absorption, stimulating follicle cells, and even helping counter DHT-related hair loss.
- Vitamin E improves hair count and scalp health through its antioxidant power, enhanced circulation, and sebum regulation, creating a growth-friendly environment.
- Usage differs; Vitamin C is water-soluble and best taken daily through foods or supplements, while Vitamin E is fat-soluble, works slower, and requires consistent intake over months.
- Vitamin C is generally low-risk aside from mild digestive issues at very high doses, while Vitamin E needs caution since excess amounts can thin blood and interfere with thyroid function.
- Trybello's Hair Repair & Anti-Stress Gummies feature vitamin C alongside biotin, AnaGain™, organic sunflower oil, and stress-fighting ingredients like L-theanine and ashwagandha to create a comprehensive approach to hair revitalization from within, backed by our 120-Day Growth Guarantee.
The Science Behind Hair Growth Vitamins
Hair loss affects nearly 50% of men and women by age 50, with oxidative stress playing a major role in follicle damage and premature aging. Free radicals from pollution, UV exposure, and daily stress attack hair follicles at the cellular level, weakening the structures that support healthy growth. This is where antioxidant vitamins become crucial allies in your hair care routine.
Both vitamin C and vitamin E function as powerful antioxidants, but they work through different pathways to support hair health. Understanding these mechanisms helps you choose the right approach for your specific needs, no matter if you're dealing with thinning hair, breakage, or simply want to maintain strong, vibrant strands as you age.

Vitamin C for Hair Growth: Properties and Benefits
Collagen Production and Hair Strength
Vitamin C is the backbone of collagen, the protein that makes up most of your hair. Strong, elastic strands owe their resilience to it, and studies show that getting enough vitamin C can noticeably reduce breakage while improving overall hair quality. With the right levels in your system, your body produces the collagen needed to keep hair healthy, flexible, and far less likely to split or snap.
Iron Absorption Enhancement
Vitamin C also plays a key role in absorbing iron, a nutrient vital for strong, steady hair growth. This is especially important for women, since iron deficiency is a common cause of thinning and shedding. By boosting iron absorption, vitamin C ensures your follicles get the fuel they need to keep hair growing thick and strong.
Dermal Papilla Cell Stimulation
On a cellular level, vitamin C even influences the tiny dermal papilla cells at the base of your follicles. These cells decide when hair grows or rests, and research shows vitamin C can encourage them to kickstart growth sooner and help strands grow longer. It’s a behind-the-scenes push that keeps your hair in its active growth phase.
Fighting Androgenic Hair Loss
Research shows that L-ascorbic acid 2-phosphate found in vitamin C may help prevent androgen-induced baldness in response to DHT (dihydrotestosterone). This finding is particularly significant since DHT is the primary hormone responsible for pattern hair loss in both men and women.
Vitamin C-rich foods like citrus fruits and berries provide natural support for collagen production and iron absorption.
Vitamin E for Hair Growth: Properties and Benefits
Tocotrienol Research and Clinical Results
Vitamin E comes in eight forms, but tocotrienols are the real stars of hair growth. In one study, people taking 100 mg daily saw a 34.5% increase in hair count over 8 months, compared to almost no change in the placebo group. The boost likely came from their strong antioxidant power, which protects the scalp from oxidative stress linked to hair loss.
Scalp Circulation and Blood Flow
Vitamin E also helps open up blood vessels and supports red blood cell production, which improves circulation to the scalp. Better blood flow means more oxygen and nutrients reach your follicles while waste gets cleared out, creating a healthier environment for growth.
Antioxidant Protection for Follicles
Since oxidative stress is tied to hair loss, vitamin E’s role as an antioxidant is key. By neutralizing free radicals, it shields follicles from damage caused by pollution, UV rays, and even chemical treatments. This protection helps maintain stronger, healthier strands.
Sebum Production and Scalp Health
Another bonus: vitamin E supports sebum production, the natural oil that keeps your scalp moisturized and balanced. Without it, dryness and irritation can creep in, potentially leading to shedding. With enough vitamin E, your scalp stays nourished and primed for growth.
Usage Guidelines
How to Use Vitamin C for Hair
The best way to get vitamin C is through food: citrus, berries, peppers, and greens usually cover your daily needs of 90 mg for men and 75 mg for women. Smokers need a little extra. Some also try it topically by mixing a bit of vitamin C serum with scalp oil a couple of times a week, but always patch-test first.
How to Use Vitamin E for Hair
Vitamin E supplements take time, at least four months, with stronger results after eight. Adults need about 15 mg a day, ideally with a fat-containing meal. For a hands-on option, mix oil from a couple of capsules with castor or coconut oil, massage it into your scalp, and rinse after half an hour.
Proper application of vitamin supplements can enhance their effectiveness for hair health when used consistently over time.
Side Effects and Safety Considerations
Vitamin C Safety Profile
Vitamin C is generally very safe, with the main side effects being mild stomach upset or diarrhea at high doses. Because it’s water-soluble, extra amounts are flushed out in urine rather than stored. Still, going over 1,000 mg a day can cause digestive issues, kidney stones in some people, or even interfere with lab tests, so the safe upper limit is set at 2,000 mg daily.
Vitamin E Precautions and Interactions
Vitamin E needs a little more caution. Too much can thin the blood, raise bleeding risks, and even lower thyroid hormone levels. One study found that very high doses of vitamin E, about 30 times above the daily 15 mg recommendation, may reduce hair growth due to hormonal effects. To stay safe, stick to the recommended amounts, especially if you’re taking blood thinners.
