Keratin Every hair lover knows this word! Because most hair beauty products on the market almost always feature keratin as an important ingredient. This is because keratin has countless benefits for hair — from making it thicker and softer, to more moisturised, shiny, smooth, and full of weight, looking vibrant and healthy.
But before diving into what keratin really is, why it's so good for hair, and how to add more to your strands — let's first get to know the structure of hair, the star of our story!
But before diving into what keratin really is, why it's so good for hair, and how to add more to your strands — let's first get to know the structure of hair, the star of our story!
Hair consists of dead cells — no life, no feeling. Its internal structure differs from person to person, causing differences in the external appearance of each person's hair — whether in colour, straight or curly, thin or thick, and so on. If you take a cross-section of a hair strand and magnify it, you will see that hair is composed of 3 layers:
– Outer layer (Cuticle)
This is the outermost part, with no colour. It acts as a shield protecting dirt from penetrating the inner layers of the hair, and helps prevent the hair from losing moisture. The outer layer accounts for about 10% of the total hair and can be damaged by improper combing, heat exposure, and chemical treatments. When the outer layer is damaged, hair becomes dry, frizzy, split, thin, and eventually breaks and falls out.
– Middle layer (Cortex)
This is where pigment is concentrated, so the cortex of the hair strand determines the colour of the hair. Not only that, it also houses proteins, keratin, and protein fibres — so it is the layer that determines how soft or flexible the hair is, depending on the amount of nutrients nourishing this layer.
– Inner layer (Medulla)
This is the core of the hair strand, which does not play a particularly important role. It is made of protein and fat. It is mostly found in people with strong hair, while people with thin hair often do not have a medulla.
Keratin is a type of protein that acts as an important structural component of human skin, nails, body hair, and hair strands. For hair, keratin resides in the Cortex layer, which is the thickest layer and the main structural component of the hair strand, with keratin making up as much as 90% of the hair — arranged in a scale-like pattern (as commonly seen in hair product advertisements) — and regulating what enters the hair cells.
When keratin in the hair is damaged, the cuticles open up, causing hair to look dry and dull, brittle, easy to break, weightless, frizzy, and flat — because damaged keratin means the hair can no longer retain moisture. The main factors that damage keratin include heat exposure, straightening, perming, and other chemical treatments.
In addition to external factors, there are also internal factors that cause insufficient keratin in the hair — such as genetics, orconsuming too little protein so that the body lacks sufficient nutrients to nourish the hair. In addition to making hair look dry and lifeless, this factor is also a cause of hair shedding, weak roots, and can eventually lead to thinning hair.
Keratin treatment is an extremely popular option for restoring soft, silky hair — whether getting a keratin treatment at a salon, or buying a keratin-containing hair treatment product to do at home. Both replenish protein back into the hair, adding weight, thickness, and shine. (The main differences are usually price and quality.) Additionally, keratin treatment can also be used as a substitute for hair straightening. Keratin treatment is therefore suitable for those who want smooth, straight hair — but don't want it to appear as flat as permanent straightening.
For those who want soft, weightful hair after a salon keratin treatment, they should not use shampoo containing SLS — as it is a harsh detergent unsuitable for hair. Additionally, you should not apply coconut oil as a hair mask after a keratin treatment, as it will cause the keratin to wash out much faster. As for how long a keratin treatment lasts, it depends on the type of keratin used at the salon — but roughly it will last about 6–8 months.
Keratin treatment is indeed one option for vibrant, beautiful hair — but it mainly focuses on fixing dry hair, split ends, and frizzy hair. For those whose hair has lost so much keratin that it has started falling out, we need to supplement keratin from within the body by adding nutrients that help boost keratin into our daily meals instead — because supplementing keratin from the outside alone is not sufficient to address hair loss.
The nutrients that help boost keratin in the hair are Biotin also known as Vitamin H or Vitamin B7 It is an important component that strengthens hair, supports the function of keratin from within, helps fortify the structure of keratin, and makes hair strong from root to tip — so hair shedding decreases as a result.
But for those with hair loss problems, simply boosting keratin function alone is often not enough. Our body also needs many other nutrients, vitamins, and minerals to help care for hair and scalp from all angles — keeping hair and scalp strong, stimulating new growth, restoring vibrancy so hair doesn't frizz, split, become brittle, or fall out easily. Which is why AloEx Dietary Supplement answers all of this perfectly — becauseit doesn't just have biotin to support keratin function, but also contains over 15 other powerful concentrated extracts in appropriate amounts, packed into 1 capsule.
