Hair loss is a problem that affects both men and women. In fact, two-thirds of all American men have are projected to have experienced some degree of hair loss by the time they are 35 years old.

For men, hair loss usually begins from the front as a receding hairline. It then works its way to the back of the head until there’s no hair left. For women, female pattern baldness doesn’t lead to complete baldness, but does affect all hairs on the scalp. This leads to thin, dry, and brittle hairs all over.

While the main culprit of hair loss is dihydrotestosterone, or DHT, there are other factors that can cause hair loss as well. Foreign contaminants like dust, dirt, chemicals, or even fungal growths can damage your scalp and lead to hair loss. Tension from tying hair or chemical from styling it can also cause damage to your hair.

While there are lots of hair loss treatment products out on the market today, By Natures Bio 7 Hair Growth oils stood out among them as an all-natural product. These oils offer a powerful yet gentle mixture of chemicals to both treat hair loss and restore your hair’s natural strength and shine.

Natural Oils

Their products are equipped to deal with all sources of hair loss problems. They include natural DHT blockers to mitigate the damage that the hormone does to your scalp. Other components, such as biotin, reinforce hairs by strengthening the keratin found in follicles.

As their brand name may suggest, By Natures uses only natural substances in their products, with a wide range of essential oils carefully selected for their healing and cleansing properties.

Bio 7 Hair Growth Oil Ingredients

This hair growth oil comes with 7 core oils, namely: monoi, pimento, green coffee, black seed, black castor, rosemary, and neem. Each of these contributes to this oil’s potency and ensured results.

Monoi oil

Monoi oil is made by submerging the petals of the Tahitian gardenia or tiaré flower in coconut oil. Its hybrid nature gives it a variety of roles in skin and hair care. Coconut oil is a powerful antibacterial substance that protects and moisturizes your scalp with a thick layer of fatty oils.

Pimento oil

Pimento oil is extracted from the pimento tree, which is indigenous to South America and the Caribbean. While there have been no concrete studies linked to its hair care benefits, many believe that pimento oil is linked to better hair growth due to its antioxidant properties.

Green coffee oil

Green coffee oil’s caffeine content may help with hair loss. Caffeine in green coffee oil is not only a natural DHT blocker, it also promotes blood flow and stimulate s hair follicle to build new hair strands. It also contains antioxidants that help protect scalp and hair from damage and promotes softer and glossier hair.

Black seed oil

Black seed oil comes from pressing the seeds of the nigella sativa, or fennel flower. While it’s most commonly found as an anti-acne product, black seed oil has been found to have hydrating, moisturizing, and wound healing properties.

Black castor oil

Black castor oil is another ingredient that has yet to be studied further. This oil differs from yellow castor oil by its extraction process; while yellow castor oil comes from cold pressing castor beans, black castor oil is extracted by roasting the beans, then applying heat. Black castor oil is known for its powerful water retention properties, making it a very effective moisturizer.

Rosemary oil

Rosemary oil is derived from the rosemary herb, which is normally used for cooking. When distilled into an essential oil, rosemary has anti-inflammatory properties that can soothe irritated skin and fight dandruff. It’s also believed to help repair nerve damage and serve as a natural DHT blocker.

Neem oil

Neem oil is produced by the neem tree’s fruits and seeds. Research on neem oil’s benefits for hair and skin care is still ongoing; but because of neem oil’s rich fatty acid and antioxidant content, it’s suggested that neem oil can serve as a powerful moisturizer and hair cleanser.

How to Use the Bio 7 Hair Growth Oil

Simply apply drops to damp or dry hair. For straight hair, use 5-10 drops instead after each wash.
