Carrier oils for hair growth
“Rosemary and biotin are essential ingredients for helping with hair growth,” Spearman said. “This oil stimulates the scalp and nourishes the follicles, protects against environmental factors and soothes an irritated scalp to treat any dandruff.”
Best Oils for Hair Regrowth
Oils like Mineral Oil, Lemon Oil, Camphor Oil, and sometimes Castor Oil and heavy oils like Olive Oil can be bad for hair, causing buildup, dryness, breakage, or dullness, especially for fine or low-porosity hair, while mineral oil clogs pores and prevents nutrient absorption.
Oils don't make your hair grow, but that doesn't necessarily mean they're bad. What they can help with is sealing in moisture, which can help with length retention because healthy, moisturized, hydrated hair is going to be less prone to breakage.
You can put hair oil on both damp and dry hair, but it serves different purposes: apply to damp hair (after washing) to lock in moisture and prep for air-drying or heat styling (with protection), while applying to dry hair (after styling) helps tame frizz, add shine, and finish your look. For deep conditioning, apply oil to dry hair before shampooing as a pre-treatment, as this allows for deeper penetration, say Real Simple and Aussie.
To speed up hair growth, focus on a nutrient-rich diet (protein, biotin, iron, omega-3s), manage stress, get regular trims to remove split ends, and stimulate your scalp with massages, all while minimizing heat and chemical damage to support the hair's natural growth cycle and prevent breakage, though genetics determine your maximum growth rate.
The "Big 3" for thinning hair, especially male/female pattern baldness, are typically Minoxidil (Rogaine), Finasteride (Propecia), and sometimes Ketoconazole shampoo, or even Microneedling, forming a multimodal approach to stimulate growth and block hormones (DHT) causing hair loss, with Minoxidil boosting circulation, Finasteride inhibiting DHT, and Ketoconazole reducing inflammation and acting as a mild anti-androgen.
If you are looking for a healthier scalp, reduced dandruff and the potential of increased hair growth - then cast your eyes on castor oil. This oil is full of ricinoleic acid, which is known to increase blood flow to the scalp and stimulate the hair follicles, whilst reducing inflammation that can trigger dandruff.
Over-oiling leads to the deposition of dirt over the hair strands and clogging of pores, causing scalp infection and more shedding of hair. Leaving oil on for over 24 hours causes dust and sweat to get clogged, thus making the scalp a breeding ground for bacteria that makes hair roots weak.
There's no single "world No. 1" hair oil, as the best choice depends on your hair needs (dryness, frizz, damage, growth), but popular, highly-rated options include Olaplex No. 7 Bonding Oil (strength/shine), Kérastase Elixir Ultime (versatile shine/smoothness), Oribe Gold Lust Nourishing Oil (overall gloss), Gisou Honey Infused Hair Oil, and natural choices like Coconut Oil (moisture/protein) or Argan Oil (softness/frizz). Olaplex is famed for repairing bonds, while Kérastase and Oribe offer luxurious shine and frizz control for most types.
Researchers found rosemary oil to be as effective at encouraging hair regrowth as minoxidil, a medication better known as Rogaine®, says Dr. Khetarpal. The small-scale study in 2015 focused on people with androgenic alopecia (male pattern baldness or female pattern baldness).
Recent clinical trials have demonstrated the efficacy of Cyperus rotundus essential oil (CREO) in reducing hair growth, with minimal side effects. CREO has been found as effective as Alexandrite laser treatments in some cases, particularly in reducing white hair.

Minoxidil (Rogaine)
It's FDA approved to treat scalp hair loss in women and men. Experts aren't entirely sure how it works, but it probably dilates (opens) blood vessels, which lets more blood flow to the hair follicles. Minoxidil is also available as a prescription pill.

For Thicker Hair: Castor and coconut oils can improve thickness and prevent breakage. For Dry or Frizzy Hair: Argan and jojoba oils are excellent for hydration and shine. For Stimulating Growth: Rosemary and peppermint oils work well to boost blood flow and follicle health.
Key vitamin deficiencies linked to hair loss include Vitamin D, B12, Biotin (B7), and Iron, with low levels of these nutrients affecting hair follicle function, protein production (like keratin), and oxygen supply, leading to thinning or shedding; however, excessive intake of some vitamins (like A or selenium) can also cause hair loss, so a doctor should confirm deficiencies via blood tests before supplementing.
Japanese scalp treatments focus on cleansing, stimulating, and nourishing the scalp to create an ideal environment for healthy hair growth. These treatments remove buildup, improve circulation, and strengthen hair follicles, helping with early signs of hair loss and thinning.
Effective treatments for some types of hair loss are available. You might be able to reverse hair loss, or at least slow it. With some conditions, such as patchy hair loss (alopecia areata), hair may regrow without treatment within a year. Treatments for hair loss include medications and surgery.
Hair growth is regulated by male hormones (androgens, such as testosterone and dihydrotestosterone), which are present in both men and women but in different amounts. Testosterone stimulates hair growth in the pubic area and underarms.
Sleep deprivation disrupts the biological hair growth cycle, prematurely pushing follicles into the shedding phase. Over time, this leads to progressive hair loss. Improving sleep consistency helps stabilise hormones, encourages new hair production, and alleviates stress - creating conditions for robust growth.
