In the diverse world of beauty and personal care, the concept of a do-it-yourself (DIY) approach has always offered a unique allure.

The prospect of concocting your own effective solutions tailored to your specific needs can be incredibly fulfilling.

One such pursuit that has captivated the attention of many, particularly those with black hair, is the crafting of a DIY hair growth serum.

This handy, homemade product is designed to support hair health and strength, and provide an overall nurturing effect, particularly for black hair which often requires extra care due to its unique texture and structure.

Whether you're seeking to reverse thinning hair, stimulate black hair growth, improve hair density, aim for thicker hair, or simply maintain luscious locks, a DIY hair growth serum can be an essential tool in your hair care arsenal.

Let's delve into how you can formulate this potent concoction right at home, and what makes it so beneficial.

What is a DIY hair growth serum for black hair?

A DIY hair serum is a homemade preparation designed to support the overall well-being of natural black hair. It's typically made from natural ingredients like essential oils, carrier oils, and sometimes plant extracts, which are known to nourish the scalp, encourage hair growth, and strengthen hair strands.

The unique structure and texture of black hair, along with the tendency for it to become dry and brittle, often make it more susceptible to breakage and damage. This is especially true for dry and damaged hair.

It is primarily due to the fact that the natural oils from the scalp find it difficult to travel along the coiled structure of the hair strand, causing it to dry out more quickly.

Therefore, the need for a custom solution like a DIY hair growth serum becomes essential.

DIY hair growth serums typically incorporate natural ingredients like castor oil and jojoba oil, which are known for their beneficial properties on scalp and hair.

Essential oils like peppermint, lavender, and rosemary are also common for their scalp-stimulating effects.

These serums can be customized to suit individual hair needs and provide a cost-effective, natural alternative to commercial products, allowing a more personalized approach to hair care.

Key benefits include:

  • Personalized care: You can customize the serum to cater to your specific hair needs and preferences, making it a truly personalized hair care solution.

  • Cost-effective: A DIY serum can be made at a fraction of the cost of commercial hair growth products, making it a more affordable option.
  • Avoids harsh chemicals: With a homemade serum, you can avoid potentially harmful chemicals found in some store-bought products that could damage your hair or scalp over time.
  • Enhances hair growth: The concentrated nutrients in DIY serums can stimulate the scalp and foster faster, healthier hair growth.
  • Promotes scalp health: Ingredients like essential oils such as almond oil and argan oil, not only stimulate hair growth but also improve overall scalp health, helping to combat issues like dryness or dandruff.
  • Strengthens hair strands: Regular use of DIY serums can strengthen hair strands, reduce breakage, and increase hair density, leading to thicker, fuller hair.

The science behind hair growth

The hair growth cycle

Hair growth is a cyclic process that includes four key phases: Anagen (growth phase), Catagen (transitional phase), Telogen (resting phase), and Exogen (shedding phase).

  1. Anagen Phase: This is the active growth stage where new hair cells are rapidly produced. This phase typically lasts between 2 and 7 years.
  2. Catagen Phase: A brief transitional stage that lasts about 2-3 weeks, during which the hair follicle shrinks and detaches from the dermal papilla.
  3. Telogen Phase: The resting stage, lasting around three months, where the hair follicle remains dormant and the detached hair is shed.
  4. Exogen Phase: The final phase, overlapping with the resting stage, when the old hair sheds and a new hair continues to grow.

Factors impacting hair growth

Several factors can influence hair growth, including genetics, age, health, diet, and lifestyle. Hormonal imbalances, stress, and certain medical conditions can also disrupt the normal hair growth cycle and cause hair loss or thinning.

Nutrients and ingredients promoting hair growth

Key nutrients and ingredients that promote hair growth include:

  • Proteins: Hair is primarily made up of a protein called keratin, so a protein-rich diet can support hair health and growth.
  • B-Vitamins: Particularly biotin and niacin, which have been linked to hair growth.
  • Vitamin E: Protects your hair from damage and supports a healthy scalp.
  • Omega-3 Fatty Acids: Nourish hair and support thickening.
  • Iron and zinc: Both nutrients help hair follicles to grow.
  • Essential oils: Like lavender, rosemary, and peppermint, stimulate the scalp and aid hair growth.

The role of hair serums in promoting growth factors

Hair serums can play a crucial role in promoting hair growth factors. They work by delivering concentrated amounts of essential nutrients directly to the hair follicle, scalp, and hair strands.

These nutrients nourish and stimulate the hair follicles, encouraging healthy hair growth. 

Moreover, they can help to balance oil production, improve blood circulation to the scalp, and protect the hair from environmental damage, all of which contribute to the overall health and vitality of your hair.

Necessary ingredients for DIY serums and their benefits 

When crafting your own DIY hair growth serum, it's crucial to understand the role of each ingredient you use. Here's a list of common natural ingredients used in these serums and their respective benefits:

1. Castor oil

Rich in ricinoleic acid and omega-6 fatty acids, castor oil is known to enhance scalp circulation and boost hair growth.

2. Jojoba oil

This oil closely resembles sebum, the natural oil produced by the scalp. Jojoba oil is excellent for reducing dryness and breakage, as it hydrates the hair and scalp effectively.

3. Peppermint essential oil

Peppermint oil can stimulate the scalp due to its cooling effect, which can boost blood flow and invigorate hair follicles, promoting hair growth.

4. Lavender essential oil

Known for its soothing properties, lavender oil can help calm an irritated scalp. It also has properties that may promote hair growth and reduce hair loss.

5. Rosemary essential oil

Rosemary oil is known for its ability to stimulate the scalp and increase local blood circulation, which can help in promoting hair growth.

6. Coconut oil

This oil is highly penetrative, reaching the hair's cortex to hydrate and strengthen the hair shaft from within. It also has antifungal properties that can keep scalp infections at bay. 

7. Aloe vera

Aloe Vera soothes the scalp, reduces dandruff, and unblocks hair follicles that may be blocked by excess oil.

It also contains vitamins A, C, and E, which contribute to cell turnover, promoting healthy cell growth and shiny hair.

8. Olive oil

Another great ingredient that you can add to this mixture is olive oil, a popular hair growth oil that nourishes the scalp and improves hair health.

Like other hair oils, it also adds extra shine to your hair. 

A step-by-step guide to making a DIY hair growth serum for black hair

hair growth oils

Creating your own DIY hair growth serum if you have black hair, is a simple, straightforward process. Here's a step-by-step guide to help you:


  • 2 tablespoons of castor oil
  • 2 tablespoons of jojoba oil
  • 2 tablespoons of aloe vera gel or aloe vera juice
  • 5 drops of peppermint essential oil
  • 5 drops of lavender essential oil
  • 2 drops of apple cider vinegar
  • 5 drops of rosemary essential oil
  • 1 small dark glass dropper bottle (to preserve the potency of the oils)


  1. Clean your bottle: Begin by thoroughly cleaning and drying your dropper bottle. You want to ensure it's sterile to keep your serum free from bacteria.
  2. Add your base oils: Start by adding the castor oil and jojoba oil to your bottle. These oils will form the base of your serum, providing intense hydration and promoting scalp health.
  3. Include essential oils: Carefully add your drops of peppermint, lavender, and rosemary essential oils to the mix. These oils not only stimulate the scalp but also provide a soothing effect.
  4. Mix the serum: Securely fasten the lid on your dropper bottle and gently shake the mixture to ensure all the oils are thoroughly combined.
  5. Store correctly: Keep your serum in a cool, dark place when not in use to maintain the effectiveness of the essential oils.

How to apply DIY hair growth serum effectively

Applying a DIY hair growth serum effectively involves more than simply spreading it over your scalp. Here are some best practices for application.

  • Apply on a clean scalp: To maximize the absorption of the serum, start with a clean and damp scalp. This ensures that there's no build-up that can hinder the serum from penetrating the hair follicles.
  • Apply directly to the scalp: The serum should be applied directly to the scalp, not just the hair. This is because the nutrients in the serum need to reach your hair follicles to stimulate growth.
  • Use a dropper: Use a dropper to apply the serum. This will help you control the amount of serum you're applying and ensure it's evenly distributed across your scalp.
  • Massage it in: Once applied, gently massage the serum into your scalp for several minutes. This helps with absorption and stimulates blood flow to the scalp, enhancing the effects of the serum.
  • Time it right: The best time to apply the serum is at night before you go to bed. This allows the serum to work its magic overnight. If you prefer to apply it during the day, aim to leave it in for at least 2 hours before washing your hair.
  • Consistency is key: Consistent application is crucial. Aim to apply the serum 2-3 times a week, or as suits your hair needs.
  • Be patient: Hair growth takes time. Don't be discouraged if you don't see immediate results. Keep consistent with your application, and with time, you should start seeing improvement in your hair health and growth.

Diet and lifestyle

Ensuring a balanced, nutrient-rich diet is integral to maintaining hair health.

This means consuming ample protein, iron, and vital vitamins like A, C, D, and E, along with omega-3 fatty acids — all essential contributors to hair growth and strength. 

Alongside a healthy diet, staying well-hydrated is crucial as it maintains overall hair health and shines from the inside out.

Moreover, regular exercise, by boosting blood circulation throughout the body including the scalp, can significantly promote hair growth.

Manage stress

Chronic stress can have a negative impact on hair health, including hair loss.

Incorporate stress management techniques into your routine, such as yoga, meditation, or any other relaxation exercises.

Protect your hair

Safeguard your hair from harsh environmental factors, including sun, wind, and chlorine in swimming pools.

Wearing a hat or scarf can help protect your hair from UV damage, and it's a good idea to rinse your hair immediately after swimming to remove any chlorine.


Caring for your hair doesn't have to be a hassle or an expensive affair.

With a DIY hair growth serum, you can create a personalized solution that nurtures your black hair, stimulates growth, and improves overall hair health. 

By combining this with complementary hair care products like the Bio-Pilixin Hair Serum, maintaining a balanced diet and healthy lifestyle, managing stress, and protecting your hair from harsh elements, you'll be well on your way to stronger, luscious locks. 

Remember, everyone's hair is unique, so experiment and adjust your serum ingredients as needed.

With consistent use and patience, you can expect to see a significant improvement in your hair's health and length.


How often should I apply the DIY hair growth serum?

Apply the serum 2–3 times per week or as your hair needs. Consistency is key for optimal results.

When will I start seeing results after using the DIY hair growth serum?

Hair growth takes time, and the results will vary for each person. However, with consistent application, you should start noticing improvements in your hair health and growth after a few weeks.

Can I use the DIY hair growth serum on treated or colored hair?

Yes, the natural ingredients in the DIY hair growth serum are generally safe for all hair types, including treated or colored hair. However, it's always a good idea to patch test any new product or ingredient on your skin first.

Will the DIY hair growth serum cure hair loss?

The DIY hair growth serum can help stimulate hair growth and improve overall hair health, which may reduce hair loss over time. However, it is not a cure for underlying medical or genetic conditions that cause hair loss. Always consult with a healthcare professional if you're experiencing significant hair loss.

What if I am allergic to one of the ingredients in the DIY hair growth serum recipe?

The beauty of a DIY recipe is its flexibility. If you're allergic to an ingredient, you can easily replace it with another one that has similar hair benefits. Always make sure to test any new ingredient on your skin before applying it to your scalp.
