Hair growth is influenced by a combination of genetic, environmental, and physiological factors. These determinants work together to promote healthy hair or contribute to hair challenges.

Factors Affecting Hair Growth:

  • Genetics: The genes you inherit from your parents are crucial in determining hair texture, colour, and growth rate.
  • Age: Hair growth slows as we age, and hair strands become thinner and weaker.
  • Hormonal imbalances: Conditions like polycystic ovary syndrome (PCOS) or thyroid disorders can impact hair growth and health.
  • Diet and nutrition: A lack of essential nutrients, especially proteins, vitamins, and minerals, can hinder hair growth.
  • Stress: Chronic stress can lead to conditions like telogen effluvium, causing hair shedding.
  • Medications and treatments: Certain drugs, such as chemotherapy, can lead to hair loss.
  • Scalp health: Issues like dandruff, fungal infections, or psoriasis can impede hair growth.
  • Environmental factors: Exposure to pollutants, sun, and harsh weather can damage hair and hinder growth.
  • Hairstyling practices: Excessive heat styling, tight hairstyles, and chemical treatments can weaken hair.
  • Underlying medical conditions: Diseases such as lupus or alopecia areata can result in hair loss.
  • Poor blood circulation: Scalp health is closely tied to blood circulation; poor flow can limit nutrient delivery to hair follicles.
  • Hormonal changes: Pregnancy, menopause, and other life events can alter hair growth patterns due to hormonal shifts.
  • Smoking: It reduces circulation and, consequently, can impair hair growth.

13 best ingredients for hair growth

1. Coconut oil

best ingredients for hair growth

Coconut oil is often used for its hydrating properties and is believed to help in moisturizing weakened hair. This amazing oil can seep into the hair, nourishing it from within, which helps reduce hair fall. It is thought that the hydrating nature of coconut oil can help mitigate damage from strong chemical products.

What to try: Scoop two spoonfuls of coconut oil and gently rub it all over your scalp. Let it sit and soak for around an hour. Afterwards, rinse it out well using a soft cleanser or shampoo. Make this a routine, doing it at least two times every week.

2. Gooseberries

Amla, or gooseberry, is a popular ingredient in traditional Ayurvedic practices. Research suggests that it can boost the activity of dermal papilla cells (DPC) in hair roots. 

Research suggests that gooseberries may play a role in maintaining the anagen phase of the hair's life cycle, which is often associated with hair length.

Here's a tip: Pour a little amla oil into your hands and work it into your scalp. Allow it to sit for at least an hour before washing it off thoroughly. For optimal scalp health, repeat this method two times a week.

3. Yoghurt

Yoghurt is packed with probiotics and can play a key role in promoting strong hair growth and shielding hair from damage. 

Research on mice has shown that yoghurt can increase the number of follicles under the skin, resulting in thicker hair, which could be relevant for human hair health.

What to do: Enjoy a bowl of yoghurt every day.

4. Fenugreek seeds

Fenugreek contains compounds that are thought to support the look of healthy hair. Research on rats has demonstrated its potential in curbing hair loss and stimulating fresh hair growth. Additionally, it's a renowned herbal solution for tackling dandruff issues.

Actionable tip: Immerse a quarter cup of fenugreek seeds in water and leave them overnight. In the morning, blend these seeds into a smooth paste and use it as a hair mask. Allow it to settle for 30-45 minutes, then wash it off with cool water. Consider doing this weekly for best results.

5. Onion juice

The rich phytochemical content in onion juice is believed to stimulate hair regrowth, making it a promising remedy for conditions like patchy alopecia areata.

Recommended action: Squeeze the juice from half an onion and sieve it to get a clear liquid. Spread this juice over your scalp and let it stay for about an hour. Afterwards, rinse it out properly using shampoo. Incorporate this treatment into your routine biweekly for optimal benefits.

6. Chinese Hibiscus 

Studies have shown that the essence from hibiscus leaves and blossoms can enhance hair growth in rats. Given these results, it might be an effective natural treatment to counter significant hair loss in people.

What to try: Crush a few hibiscus flowers and some leaves until you get a thick paste. Blend this with coconut oil. Coat your hair and scalp with this mixture and leave it on for around 60 minutes. 

Afterwards, cleanse your hair using your regular shampoo. It's recommended to repeat this process weekly for noticeable results.

7. Green tea

Loaded with polyphenols and powerful antioxidants, green tea can be a boon for your tresses. Its active ingredients are believed to stimulate dermal papilla cells, potentially mitigating hair shedding.

Actionable tip: Infuse a green tea bag in a cup of hot water and savour the brew. For optimal benefits, consider drinking green tea once or twice daily.

8. Rosemary oil

Research from Kinki University suggests that rosemary oil might bolster hair growth, as seen in experiments with mice. This gives hope that it could also effectively promote hair growth in humans.

Suggested action: Conduct a patch test before diving in to ensure you don't react adversely to rosemary oil. Given the potency of essential oils, it's wise to blend a few drops of rosemary oil with a carrier oil. Massage this concoction onto your scalp and leave it on for around an hour before rinsing it out.

9. Geranium oil

Research indicates that geranium oil can stimulate hair growth in mice, specifically through its positive influence on dermal papilla cells. However, as some might be sensitive to geranium oil, it's always a good idea to do a patch test first.

Recommended steps: Pour a small amount of geranium oil into your hand and gently rub it over your scalp. Allow it to soak in for around an hour. Afterwards, wash your hair with a gentle shampoo. Make this a weekly routine for best results.

10. Ginseng oil

Ginseng has been spotlighted in studies for its potential to stimulate human hair follicles and encourage hair growth. 

However, some users have reported side effects like dizziness, nausea, or headaches, and it can be produced for some. Hence, it's essential to use ginseng with awareness.

Actionable steps: Measure out a small quantity of ginseng oil and softly work it through your scalp. Let it seep in for approximately an hour. Afterwards, cleanse your hair using a gentle shampoo. Integrate this treatment into your routine biweekly for optimal benefits.

11. Fish Oil 

Packed with omega-3 fatty acids, fish oil can be a game-changer for hair growth. The presence of docosahexaenoic acid (DHA) in fish oil supplements has been shown to stimulate hair growth by positively affecting the dermal papilla cells in the scalp. 

This could counteract hair thinning and baldness issues. However, seeking advice from your dermatologist before incorporating fish oil supplements into your routine is crucial.

Actionable tip: After consulting your dermatologist, take a daily fish oil supplement. For direct application, massage a bit into your scalp, wait an hour, then rinse with mild shampoo. Use weekly, but do a patch test first.

12. Caffeine 

best ingredients for hair growth

Predominantly found in coffee, caffeine has been spotlighted in studies for its potential to extend the hair shaft and invigorate hair growth by lengthening the anagen phase. This offers hope in countering hair thinning and baldness.

Actionable tip: Prepare a warm cup of coffee and enjoy it daily. However, be cautious not to overindulge, considering coffee's rich caffeine content.

13. Argan oil

Argan Oil Originating from the argan tree native to Morocco, argan oil has long been celebrated for its nourishing properties. Rich in essential fatty acids and antioxidants, this golden elixir has been proven to fortify hair, making it resilient against breakage, thereby promoting healthier hair growth. It is a natural remedy against hair thinning and damage challenges.

Actionable tip: Regularly apply a few drops of pure argan oil to your hair and scalp. This not only moisturizes but also strengthens your locks. For deeper nourishment, look for hair products enriched with argan oil.

How can you prevent hair loss?

To prevent hair loss, maintain a balanced diet rich in essential nutrients, avoid harsh hair treatments, manage stress, and ensure you use the right hair care products. Regularly massaging the scalp and preventing tight hairstyles can contribute to healthier hair growth.

Here's what you can do about preventing hair thinning and loss:

  • Maintain a diet rich in iron, protein, and vitamins.
  • Avoid excessive heat styling and chemical treatments.
  • Manage stress through meditation, exercise, and relaxation techniques.
