Soon you’ll know what we mean when we say that these products are very simple yet very effective. We will also conclude with what we personally think about these products. But before we dive deeper, let us know some facts about hair loss and hair growth solutions.

Hair loss

There are several hair problems anyone can have. Some of them are itching, flaking, dryness, frizziness, split ends, damage, and greying. But one of the more troublesome for almost anyone is hair thinning or hair loss.

People normally lose 50 to 100 hairs a day. This goes unnoticed as new hairs grow just as fast. However, when fallen hair is not replaced, one suffers hair loss. According to the American Academy of Dermatology, around eight million American adults experience this condition. You are not alone.


The most common cause of hair loss is androgenic alopecia or male pattern baldness. This genetic condition affects both men and women and can start as early as their teens or early 20s. Other causes include emotional and physical trauma, stress, harmful hair treatments, and vitamin and mineral deficiencies.

Hair growth solutions

Lifestyle changes such as a balanced diet, regular exercise, and sufficient rest help reverse hair loss. There is also an abundance of best hair growth products on the market today. Among them are dietary supplements like Dasgro Hair Formula and Nutrafol vs Viviscal. There are also product lines that produce shampoos, conditioners, and topical solutions that fight hair loss like Shapiro MD.

Another emerging hair growth solution uses safe, painless, and non-invasive laser hair therapy treatment. However, there is a simple technology that utilizes your body’s natural healing mechanism to promote hair growth. It’s called a derma roller and castor oil for hair loss. And it’s scientifically shown to be more effective than the more popular alternatives.

What is a derma roller?

No products found.

Let us talk about the first product on the derma roller and castor oil combo. A derma roller is a small handheld device with a rolling cylinder covered in small needles known as microneedles. These needles vary in size from 0.25 mm to 1.5 mm and are used to inflict minor injuries to the surface of your skin. If it sounds scary, do not worry because this method is backed up by research to be safe and to have many benefits for the skin, including your scalp.

Derma rollers are traditionally used to reduce fine lines and acne scars. But just recently, people are starting to use it to treat hair loss. The reaction it initiates in the skin is actually an important process to promote hair regrowth.

As the needles inflict micro-wounds on the surface of your skin, your body naturally responds by healing and repairing itself. It then produces collagen, which is an essential protein that makes up your skin and your hair follicles.


Your body is a healing machine; injuries are prioritized for more blood flow and nutrients. This is what happens when a derma roller inflicts micro-traumas on the scalp. Blood flow to the area is stimulated to bring more nutrients, and this process, together with collagen production, is an ideal environment for healthy hair growth.

But we are not done yet, because, as a topping to derma rollers, there is a special add-on that makes the benefits of these devices even more effective! Here comes the catalyst for healthy hair growth, castor oil.

What is castor oil?

Now, let us get to know the second product on the derma roller and castor oil combo. Castor oil is used for thousands of years for its medicinal, industrial, and pharmaceutical uses. For the specific purpose of encouraging hair growth, castor oil promotes wound healing, reduces inflammation, and is a natural moisturizer. Castor oil is a common ingredient in the best hair grease for black hair products and hair growth oils like Bio 7 and Essynaturals hair growth oil.

Using castor oil after derma rolling encourages faster healing of the micro-wounds. The ricinoleic acids, omega acids, and antioxidants it contains improve blood flow and deliver nutrients to the scalp, which catalyze growth and improve the health of your hair. That is the derma roller and castor oil for the hair loss combo we are discussing!

How to use derma roller and castor oil for hair loss?

Step 1: Clean and dry your scalp

Make sure that your scalp is clean and dry. Derma rollers are best used after a bath on shampooed hair.

Step 2: Sterilize your derma roller

It is very important that your derma roller is sanitized before use. Rinse the head of the roller with disinfecting liquids such as hot water, soap, or alcohol.

Step 3: Roll 4-5 times in different directions

Start from the edge of your hairline or on the region you want to focus. Roll 4-5 times vertically, horizontally, and diagonally. Apply just the right amount of pressure to feel a tingling sensation, not pain.

Step 4: Apply castor oil to your scalp

Massage your scalp with a small amount of castor oil after rolling. It is not recommended to put oil on your derma roller.

Step 5: Clean, sanitize and dry your derma roller

It is best to clean, sanitize and dry your derma roller after use.

Step 6: Avoid any irritating substances

Only style, color, or treat your hair 24 hours after derma rolling, as these may irritate your scalp.
