By Althea Gooden, Trichologist
As a Trichologist, one of the most common concerns I hear—especially here in 2020 is, “What can I take to help my hair grow?” While topical treatments and proper hair care routines are important, true hair growth begins from within. Healthy hair cannot exist without a healthy scalp, and a healthy scalp depends heavily on the right balance of vitamins and minerals.
Hair Growth Starts at the Scalp
Your scalp is living skin, rich with blood vessels and hair follicles that require consistent nourishment. Each hair strand grows from a follicle, and that follicle depends on oxygen, blood flow, and nutrients to function properly. When the body lacks essential vitamins or minerals, the scalp is often one of the first places where imbalance shows up through shedding, thinning, dryness, breakage, or slow growth.
Key Vitamins That Support Hair & Scalp Health
Vitamin A
Vitamin A supports the production of sebum, the scalp’s natural oil. Sebum keeps the scalp moisturized and protects hair strands from dryness and breakage. However, balance is key—too much Vitamin A can actually contribute to hair loss.
B-Complex Vitamins (Especially Biotin – B7)
B vitamins help with red blood cell production, which delivers oxygen and nutrients to the scalp. Biotin, in particular, supports keratin production—the protein that makes up hair. Deficiency can lead to brittle hair and excessive shedding.
Vitamin C
Vitamin C is essential for collagen production, which strengthens hair strands. It also improves iron absorption, a mineral crucial for preventing hair loss, especially in women.
Vitamin D
Low Vitamin D levels have been linked to hair thinning and certain forms of alopecia. Vitamin D helps activate hair follicles and supports the hair growth cycle.
Vitamin E
This antioxidant improves blood circulation to the scalp and helps reduce oxidative stress, which can weaken follicles and slow growth.
Essential Minerals for Strong, Growing Hair
Iron
Iron deficiency is one of the most common causes of hair loss I see in my practice. Iron helps red blood cells carry oxygen to hair follicles. Without enough iron, follicles may enter a resting phase, leading to increased shedding.
Zinc
Zinc supports tissue growth and repair, including the scalp. It also helps maintain the oil glands around hair follicles. Low zinc levels can cause hair thinning, scalp irritation, and slow regrowth.
Magnesium
Magnesium helps reduce inflammation and supports protein synthesis. Chronic stress can deplete magnesium, which may indirectly affect hair growth.
Selenium
This mineral supports scalp health and protects against oxidative damage. Like Vitamin A, selenium must be taken in moderation.
Why Supplements Alone Are Not Enough
While supplements can be helpful, they are not a magic fix. Hair loss and scalp disorders are often multifactorial stress, hormonal changes, medical conditions, and poor hair practices all play a role. This is why I always recommend a professional scalp assessment before starting supplements. Taking the wrong vitamins, or taking too much, can do more harm than good.
A Trichologist’s Perspective
Althea Gooden Trichology, I emphasize a holistic approach:
Proper nutrition Targeted supplementation (when needed) Healthy scalp care routines Gentle hair practices
When the scalp is nourished internally and cared for externally, hair has the best chance to grow, strengthen, and thrive.
Final Thoughts
Healthy hair is not just about what you put on your hair it’s about what you put into your body. Vitamins and minerals are foundational building blocks for scalp health and hair growth, and understanding your individual needs is key.
If you’re experiencing persistent shedding, thinning, or scalp concerns, consult a Trichologist who can guide you safely and effectively on your hair journey.
Healthy scalp. Healthy hair. Informed care.
