Bio 7 Hair Growth Oil Reviews: 7 Oils vs Hair Loss

While many hair loss treatment products are on the market today, By Natures Bio 7 Hair Growth oil stands out among them as an all-natural product.

This hair growth oil promises to treat hair loss and restore your hair’s natural strength and shine. But does it live up to the hype?

Bio 7 Hair Growth Oil Overview

By Natures Bio 7 Hair Growth Oil 2 Oz 2 pack

By Natures’ Bio 7 Hair Growth Oil is a formula concocted with 7 powerful natural ingredients and essential oils. Its main promise is to help regrow hair by increasing blood flow to your scalp to encourage hair growth.

Aside from that, it also serves as a powerful conditioner that moisturizes hair and nourishes it with nutrients needed to create stronger hair strands. It also aims to protect hair from future damage and keep hair shiny and youthful looking.

Bio 7 Hair Growth Oil Active Ingredients

To achieve these results, BY Natures has infused its Bio 7 formula with seven essential oils. Below I’ll show you the benefits of each oil to help you better understand how it works.

Monoi oil

Monoi oil is made by submerging the petals of the Tahitian gardenia or tiaré flower in coconut oil. Coconut oil is a powerful antibacterial substance that protects and moisturizes your scalp with a thick layer of fatty oils. Monoi oil’s hybrid nature gives it a fragrant yet beneficial role in skin and hair health.

Pimento oil 

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

Green coffee oil 

Green coffee (Coffee Arabica Oil) oil’s caffeine content may help with hair loss. Caffeine in green coffee bean oil is a known stimulant, and studies show that it can also stimulate new hair growth. It also contains antioxidants that help protect the scalp and hair from damage and promotes softer and glossier hair.

Black Cumin Seed Oil

Black cumin 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 cumin oil has been found to have hydrating, moisturizing, and wound-healing properties.

Black castor oil

Ricinus communis, or 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. This is a common ingredient found in the best hair grease for black hair products.

Rosemary oil

Rosemary (Rosmarinus Officinalis) oil is derived from the rosemary herb, which is usually 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 be a natural DHT blocker.

Neem oil 

Neem oil (Azadirachta indica) 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, neem oil can serve as a powerful moisturizer and hair cleanser.

Other Ingredients:

Vegetable Squalene, Aloe Barbadensis (Aloe Vera) Extracts, Phospholipids, Jojoba Oil (Simmondsia Chinensis ), Argan Oil (Argania Spinosa Nut Oil), Butyrospermum Parkii (Shea Butter), Fragrance (Parfum).

How to Use the Bio 7 Hair Growth Oil

  • Start with dry or damp hair.
  • Apply the oil directly on thinning or balding scalp.
  • Use your fingers to massage your head in a circular motion for 5 minutes.
  • Let the oil sit in your hair for 30 minutes before washing it off with a mild shampoo.
  • For best results, massage your scalp with hair oil at least 2-3 times weekly.
  • Note: Always apply the oil to damp hair. This will help seal moisture and prevent the hair from becoming too dry.

Possible Side Effects

Bio 7 Hair Growth Oil is a popular product that promises to help users grow thicker, fuller hair. However, there are some potential side effects that users should be aware of before using the product.

First, the oil contains nuts, so it’s unsuitable for people with nut allergies. Second, the oil contains stimulating ingredients that could irritate people with sensitive scalps.

As with any new product, it’s always best to consult your doctor and do a patch test before using it all over your head.
