The science behind hair growth & how oil can help?
Understanding the natural cycle of your hair is crucial to choosing the right oil and maximizing its benefits. Here's a breakdown of the hair growth cycle:
- Anagen (Growth Phase): This phase last anywhere from 2-7 years. During this time, your hair follicles are in overdrive, producing new hair cells and fueling glorious growth.
- Catagen (Transition Phase): This short (2-4 weeks) phase marks the beginning of the end for the growing hair. The follicle detaches from the blood supply and growth slows down.
- Telogen (Resting Phase): For 3 months or so, the hair strand rests and eventually sheds to make way for new growth. It's normal to lose around 50-100 hairs per day during this phase.
Hair growth oils work in 3 main ways:
- Nourish the scalp: A healthy scalp is a happy scalp, and happy scalps promote healthy hair growth. Oils rich in vitamins and fatty acids can create a thriving environment for hair growth.
- Improve blood circulation: Scalp massages with oils can increase blood flow, delivering essential nutrients to follicles and stimulating growth.
- Reduce breakage: Strong, healthy hair is less prone to breakage, giving the illusion of faster growth. Oils can add moisture and strengthen the hair shaft.

How to choose the right hair growth oil?
Finding the perfect hair growth oil can feel like searching for the Holy Grail of hair care. Here are the key factors to consider:
Know Your Hair Type
Just like snowflakes, no two heads of hair are exactly alike. Understanding your hair type (fine, thick, curly, etc.) is crucial. Fine hair benefits from lightweight oils like coconut oil or grapeseed oil, while thicker hair can handle richer oils like castor or avocado.
Consider Your Scalp Condition
A healthy scalp is the foundation for healthy hair growth. If you have a dry scalp, opt for moisturizing oils like coconut or almond. For a greasy scalp, choose lighter oils like jojoba or rosehip. If you deal with dandruff, look for oils with antifungal properties like tea tree or rosemary.
Target Your Hair Goals
Hair growth oils offer a variety of benefits beyond just length. For hair density and thinning hair, consider castor or rosemary oil. For shine and manageability, argan or grapeseed oil might be your best bet. If you want to combat breakage and split ends, look for oils rich in Vitamin E, like almond or avocado.
Read the Label Like a Pro
Not all oils are created equal! Look for products with natural, organic ingredients and avoid harsh chemicals or sulfates. Many oils are infused with additional beneficial ingredients like biotin or essential oils. Choose ingredients that target your specific hair goals.
Patch Test Before You Invest
Yes, even natural ingredients can cause sensitivities. Do a patch test on a small area of your inner arm before applying the oil to your scalp or hair.
Don't be afraid to experiment and mix different oils to create your personalized hair growth potion. Just remember to start with a small amount and gradually increase as needed.
How to apply hair oil?
Here's a simple routine you can follow to get the best results from your oil:
1. Prep your hair
Apply a few drops (less in more) of the oil to dry hair for deep penetration. If you're using it for heat protection, you can apply a small amount to damp hair as well.
2. Warm the oil (optional)
Gently warming the oil can make it easier to apply and distribute throughout your hair. You can do this by placing the bottle in a warm (not hot) water bath for a few minutes.
3. Start with a small amount
Dispense a dime-sized amount of oil into your palm. Rub your palms together to warm and distribute the oil.
4. Focus on the scalp and ends
Apply the oil to your scalp first, using your fingertips to massage it in with gentle circular motions. This helps stimulate blood circulation and nourish the scalp. Then, work the remaining oil through the mid-lengths and ends of your hair.
5. Apply more if needed
If your hair is very dry or thick, you can apply a little more oil. Be mindful and avoid oversaturation, especially near the roots.
6. Leave-in or pre-wash
You can use hair oil as a leave-in treatment or a pre-wash treatment.
- Leave-in: Apply a very small amount to damp or dry hair, focusing on the ends, to add shine and tame frizz.
- Pre-wash: Apply the oil more generously to your hair and scalp, leave it on for 30 minutes to a few hours (or even overnight), then shampoo and condition as usual.
7. Cover your hair (optional)
If you're using hair oil as a deep treatment, you can cover your hair with a shower cap or wrap it in a warm towel to help the oil penetrate further.
8. Wash and condition
If you applied the oil as a pre-wash treatment, shampoo and condition your hair as usual. You might need to shampoo twice to remove all the oil.

Frequently asked questions
How long does it take for hair to grow from hair growth oil?
Hair growth oil itself won't dramatically speed up growth, but it can contribute to a healthy scalp which supports natural hair growth rates. You'll likely see results in 3-6 months with consistent use. For best results, combine with a hair growth serum or hair loss treatments.
Can hair growth oils cause any side effects or scalp issues?
While hair growth oils are generally safe for most people, they can cause side effects in some cases. These may include allergic reactions, scalp irritation, or exacerbation of scalp conditions like seborrheic dermatitis.
Are there specific hair growth oils recommended for different hair types?
Yes, different hair types can benefit from specific types of oils. For instance, lightweight oils like argan or jojoba are excellent for fine or oily hair as they won't weigh hair down or exacerbate oil production. Thicker, coarser hair may benefit from richer oils like castor or coconut oil, which provide more intense hydration and nourishment.
