KeratinMD Hair Building Fibers Finishing Spray

The hairs are keratin stems with a tubular structure that is born at the bottom of a deep and complex invagination of the epidermis: The so-called hair follicle, whose lower end reaches the deep dermis and even the subcutaneous cellular tissue. The hair producing zone is the bulb, widened area at the base of the follicle in which the hair matrix is housed with the processes of cellular keratinization and resting in a very vascularized dermal papilla.

The hair shaft includes all visible hair located above the scalp and consists of 3 circular layers. In the inner zone, the medulla is located and around it, the cortex is located. In the outermost portion of each hair is the cuticle, formed by very thin cells that are responsible for holding the hair and anchoring it inside the follicle.

Your hair is composed of 80% keratin which is in its outer layer. In general, keratin is responsible for the protection and has a significant influence on the appearance of your hair. Keratin-rich hair will be brighter, elastic, and stronger.

The shape and texture of the epidermis, hairs, nails, feathers, and even the horns of animals are very different, however, all of them are formed primarily by the same compound, keratin. Keratin is a protein with fibrous structure, very rich in sulphur. There are two types:

Your hair is made of alpha keratin. Keratin fibrils that are in your hair adopt a helical shape when twisting, joined by disulphide molecular bridges, wrapped by an outer sheath. The main amino acids that make up this protein are cysteine, lysine, arginine, aspartic acid, and glutamic acid. All of them can be obtained from natural sources either for topical use or through food.

Keratin in the hair wears out and loses its protective function against the environment (pollution, sun rays, etc.) Bad hygiene and hair treatment habits, such as the use of aggressive shampoos and chemical abuse as dyes, hair straighteners, and dryers also weaken your hair, wearing down keratin. In these cases, the keratin in the hair suffers and causes frizzy, dry, and matte hair.

The cosmetology industry has manufactured several products to strengthen your hair by providing and protecting keratin naturally. KeratinMD Hair Building Fibers Finishing Spray is one among them.

Not sure what it is and what it will do for your hair? This is what this KeratinMD Hair Building Fibers Finishing Spray review will cover in detail.

KeratinMD Hair Building Fibers Finishing Spray Ingredients

Therefore, they are usually the most recommended for people with very sensitive or atopic skin, in children, and pregnant women.

KeratinMD Hair Building Fibers Finishing Spray is made from natural ingredients of botanical origin. It is a gluten-free product. Here is a list of all the ingredients:

Water, panthenol, camellia sinensis leaf extract, polyurethane-48, mentha spicata leaf oil, fragrance, propylene glycol, diazolidinyl urea, and iodopropynyl butylcarbamate.

The major ingredients include:

1. Camellia Sinensis Leaf Extract

It is a plant whose leaves and sprouts are used to make green tea. It originally comes from Southeast Asia, including southern China, although today it is grown both in tropical and subtropical regions around the world. It is one of the 50 fundamental herbs used in traditional Chinese medicine.

It has several benefits for your health and among its properties is that of being antioxidant, purifying, and rejuvenating. Green tea is loaded with vitamins A, D, E, C, B3, B5, B7, and K, manganese and other beneficial minerals such as zinc, chromium, and selenium. It is a very effective natural ingredient to keep the scalp in good condition. It brings strength and shine to the hair, and can help relieve dandruff, psoriasis, and other scalp irritations.

2. Mentha Spicata Leaf Oil

Peppermint is an aromatic herb, which is used in cooking but has multiple uses ranging from insect repellent to breath freshener. This plant has a cosmopolitan distribution and is found in Europe, Asia, Africa, Oceania, and America.

The best thing is its excellent aroma. It has anti-inflammatory, antibacterial, and antifungal properties so it is widely used in the pharmaceutical and cosmetic industries. It moisturizes the hair reducing dryness of the scalp helping you to have a healthy scalp.

Among the beneficial components of mint for your hair and scalp are vitamin C, vitamins of group B (B1, B2 and B3); beta-carotene (antioxidant component essential for the production of vitamin A); minerals such as calcium, phosphorus, iron , and magnesium; and flavonoids (antioxidants that reduce the action of free radicals.)

3. Panthenol

After absorption, this alcohol is metabolized by the skin tissue to become Pantothenic Acid, also known as vitamin B5. The lack of this vitamin causes the hair to be thin, with a lack of shine, brittle, and can even cause it to fall out. Thanks to its moisturizing properties, it is mainly used to improve the appearance and soften the skin.

It also helps produce coenzyme A (CoA) which is important for cellular respiration and is considered critical in the metabolism and synthesis of carbohydrates, proteins, and fats. Vitamin B5 is considered very beneficial for the nutrition of hair follicles.

Panthenol serves to brighten your hair without appearing sticky. Once applied it remains on the hair shaft allowing moisture retention, avoiding the sensation of dryness and fragility. Other properties include that it reduces the formation of brittle tips, prevents damage from excess heat provided during drying, and regularizes the pilosebaceous function.

How to Use KeratinMD Hair Building Fibers Finishing Spray

The manufacturer suggests using the spray after applying the KeratinMD Hair Building Fibres by spraying all the hair to fix the product. It also warns us that although its effect is lasting it can be used more than once a day or every day, recommending its long-term use.
