The cause of brittle hair

Hair can be naturally fragile and therefore break very easily. Brittle hair is often associated with rough texture, split ends and dull strands. This condition can be caused by several factors, including excessive heat exposure, exposure to harsh chemicals, nutrient deficiency, lack of hydration, hormonal changes, or overall poor hair health. It is important to understand the causes of brittle hair so that you can treat it effectively and maintain healthy, shiny hair.

Dietary deficiencies


A hair in poor condition can be an indicator of a nutritional deficiency or a health problem.

Hair is naturally made up of a protein called keratin, which protects it from external aggressions.

This protein is created naturally in the body, but this implies in your daily diet, an adequate protein intake.

Chronic hair loss, thin and dull hair can be the result of iron deficiency. Lack of iron is very common, especially in women.

Do not panic, these symptoms stabilize when the cause that triggers them disappears. However, you have to be patient and allow about 3 months for the body to replenish its iron stock.

Mechanical causes


Frequent styling with a recurrent source of heat, coloring, bleaching, perms… All actions that transform the natural appearance of the hair attack it and therefore damage it, especially when these actions are repeated over the long term! Especially when the hair is wet, it is more vulnerable since the cuticle is softened and is unprotected.


Environmental causes


The sun and the heat dry out and damage the hair, in particular because of the UV rays which can deteriorate the structure of the hair.

An environment that is too humid opens the hair cuticles and exposes them to various harmful effects such as environmental pollution.

Hair care

Hair care can do wonders for damaged hair. Damaged hair can be caused by a variety of factors, such as over styling, exposure to harsh chemicals, use of hair dryers and straighteners, and even poor diet. Damaged hair can look dull, brittle, dry and have split ends. Fortunately, there are a variety of hair treatments that can help restore health and shine to damaged hair.


  • A mild shampoo is a great starting point for taking care of your damaged hair. Mild shampoos are formulated to gently cleanse the hair, without stripping the natural oils that protect the hair. Mild shampoos can also help reduce frizz and deeply nourish hair. It is important to choose a shampoo that suits your hair type and your specific needs.

  • Conditioners and hair masks are also beneficial hair care products for damaged hair. Conditioners help hydrate and detangle hair, while hair masks are designed to deeply nourish hair and help repair it. Hair masks can be applied once a week or every two weeks, depending on the severity of the damage.

  • Vegetable oils are also a great way to take care of your hair.

The benefits of hair oils

Hair oils offer a natural solution to nourish and protect your hair. They can help restore moisture to the hair. Damaged hair often needs extra hydration to regain its health and vitality. Hair oils are rich in fatty acids and vitamins that help deeply moisturize the hair. They also help prevent hair dehydration by forming a protective barrier around the hair shaft. Hair oils are especially beneficial for people with dry, frizzy, or damaged hair that needs extra moisture to regain its shine.
They are rich in essential nutrients and vitamins for the hair. For example, coconut oil contains lauric acid, a saturated fatty acid that penetrates deep into the hair shaft and helps prevent breakage. Argan oil is rich in vitamin E and antioxidants that help nourish hair and prevent free radical damage. Olive oil is also a popular hair oil that is rich in fatty acids and vitamins A and E, which help nourish and moisturize hair.


Each hair oil offers unique benefits, but they all have in common the ability to nourish and protect the hair.
Hair oils can also help reduce hair breakage. Damaged hair is often brittle and breaks easily. Hair oils help strengthen hair from within by penetrating deep into the hair shaft. They also help protect hair against future damage by forming a protective barrier around the hair shaft. Hair oils also help smooth hair cuticles, which helps prevent frizz and makes hair more manageable.


There are hair oils for all hair types, curly, curly, straight, frizzy… As seen above, natural oils are therefore full of virtues for your hair! To be applied as a mask in the form of an oil bath before shampooing, your hair will thank you!

Improve hair quality with zinc


Zinc is an essential trace element for the body and the beauty of skin and hair. It plays an essential role in the synthesis of keratin and collagen . A sufficient supply of zinc helps maintain beautiful hair, prevents breakage and allows good growth.

A sufficient, healthy and balanced diet makes it possible to meet the body's zinc needs, but these reserves are fragile and easy to empty (tobacco, stress, alcohol, consumption of tea or coffee, etc.).

Zinc deficiency is easy to recognize: hair loss, acne, dry skin, fatigue, digestive disorders...
