Which Vitamins Actually Boost Hair Growth

Which Vitamins Actually Boost Hair Growth

Mar 17, 2026

When it comes to boosting hair growth, limitless options exist on the market, and it’s near impossible to pick which vitamin to take, which issue to target, or where to even start. In order to create a truly effective hair growth product, we teamed up with physicians to dive into the science behind hair growth AND hair loss.

To understand what truly creates a full head of fast growing hair, we had to examine the factors that prevent it. Hormonal shifts, nutritional deficiencies, tension, and stress all have monumental effects on hair loss, in addition to disrupting the hair growth cycle.

In fact, periods of intense stress have been shown to halt hair growth entirely, shifting follicles from their natural growth straight into a resting and shedding phase. Luckily, this phenomenon is reversible as long as stress levels return to normal, which is why we incorporated ashwagandha root extract, an herb used to reduce stress and cortisol levels, into LHC’s Hair Growth Vitamin formula.

Speaking of stress, inflammation of the scalp occurs due to a variety of factors, including tight hairstyles and harsh hair products, and in turn damages hair follicles in addition to disrupting the hair growth phases the same way emotional stress does, often resulting in alopecia. Both magnesium and grape seed extract have been shown to alleviate inflammation of the scalp, with magnesium reducing follicle clogging and breakage and grape seed extract soothing tissue damage and reducing swelling.

When it comes to hormonal hair loss, including female pattern baldness, one of the main causes is the release of DHT (dihydrotestosterone), a hormone that shrinks hair follicles. While daunting and often permanent, DHT production can be blocked with saw palmetto fruit, nettle leaf extract, and zinc (other key ingredients of ours), with clinical studies showing both increase in hair count as well as slowed hair loss.

Last but not least, nutritional deficiencies cause drastic hair loss, and in the era of GLP-1’s, this phenomenon has only worsened. While no supplement or vitamin can replace an insufficient diet’s effect on hair loss, many nutrients are vital to a healthy head of hair, including adequate protein and fat intake. Once that’s been achieved, magnesium, folic acid, and vitamin B2 all aid the body in protein synthesis, which converts dietary protein into keratin, the main component of hair.

Once hair loss has been addressed, it’s time to boost hair growth, which requires a multi-step plan for best results. Our approach includes optimizing scalp health, boosting collagen production, and stimulating new growth!

A healthy scalp requires both proper blood flow and a delicate balance of moisture! Optimizing this includes both healthy habits (washing often enough, scalp massage) as well as nutrients, including Vitamin A for balancing sebum production for moisture and Vitamins B3 & E for boosting scalp circulation.

Collagen supports hair growth by providing the building blocks necessary to create new hair, while strengthening existing follicles. It also improves the elasticity of each strand of hair, preventing breakage, in turn reducing shedding and boosting hair density. Vitamin C has been shown to directly boost collagen production naturally!

When it comes to stimulating new hair growth, each follicle must transition from the resting phase to the growth phase, a function completely dependent on Vitamin D3. As new hair grows, biotin and vitamin B12 work together to create new, strong cells at a higher rate, resulting in a boost of healthy hair growth!

Believe it or not, we’ve taken painstaking care to include every single nutrient mentioned above in LHC’s Hair Growth Vitamins, because healthy hair is so much deeper than simply adding one nutrient to your diet. By addressing each phase of your hair’s growth cycle, your scalp’s health, and easing stress and inflammation, we’re here to bring you your longest, strongest hair yet.
