The different hair types and how to recognise yours

Have you ever wondered why some hair products never seem to work for you, while they work wonders for others? The answer often lies in your hair type. Knowing your hair type is essential for an effective hair routine. In this article, we explore the different hair types, how to identify them and the best care for each one. Armed with this knowledge, you can say goodbye to bad surprises and welcome healthier, more beautiful hair.

UNDERSTANDING HAIR TYPES

The different hair types

Hair is classified into several categories, with 4 main hair types based on texture, thickness and structure, each divided into sub-categories. Here is an overview of the main types:

Straight hair (Type 1)

Straight hair has a straight texture with no curls. It is generally shiny because the scalp's natural oils spread easily along the hair shaft.

• Type 1A: Very straight and fine, often flat and lacking volume.
• Type 1B: Slightly thicker with a little more volume.
• Type 1C: Thick and coarse, but still straight.

For straight hair, the Immortelle Infused Hair Oil™ is ideal as a finishing treatment to add instant shine without weighing hair down.

Wavy hair (Type 2)

Wavy hair forms soft S-shaped waves. It can range from fine to thick.

• Type 2A: Loose, fine waves that are easy to style.
• Type 2B: More defined waves with a slightly rougher texture.
• Type 2C: Thick waves, often frizzy.

To keep your waves defined and frizz-free, the Immortelle Infused Hair Oil™ can be used before styling or added to a nourishing mask.

Curly hair (Type 3)

Curly hair has well-defined curls that can range from loose to tight.

• Type 3A: Large, loose curls that are easy to style.
• Type 3B: Tighter, more voluminous curls.
• Type 3C: Very tight, dense curls, often frizzy.

For well-nourished, defined curls, the Immortelle Infused Hair Oil™, with its ultra-natural and antioxidant ingredients, is perfect for redefining and illuminating the hair fibre.

Coily hair (Type 4)

Coily hair is very tight and can form tiny spirals or zigzags.

• Type 4A: Very tight S-shaped coils.
• Type 4B: Z-shaped coils with a drier texture.
• Type 4C: Very tight, highly defined coils, often with a very dry, fragile texture.

The Immortelle Infused Hair Oil™ is a major asset for coily hair, bringing intense hydration and protection against dryness thanks to its argan, coconut and jojoba oils.

It is entirely possible to have several hair types, growth patterns or textures. For example, very curly underneath and almost straight on top. This can be natural, but it can also be due to our environment or daily routine, which affects the texture of our hair in some areas more than others.

HOW TO RECOGNISE YOUR HAIR TYPE?

Identifying your hair type

Identifying your hair type may seem complicated, but here are a few simple steps to help:

Wash your hair

Start by washing your hair with a gentle shampoo to remove all product residue. Don't condition your hair after shampooing so you can observe its natural behaviour.

Let your hair air-dry

Don't touch your hair while it dries so you don't disturb its natural structure. Let it dry completely in the open air.

Examine your hair

Once dry, observe the texture and pattern of your hair. Compare it with the descriptions above to determine which type it matches. Don't forget to assess density (amount of hair) and thickness (size of each strand).

Practical tips

• Use a mirror: Look at your hair up close and from a distance to see both the big picture and the details.
• Ask for an outside opinion: Sometimes a second opinion can help confirm your hair type.

Hair care for your hair type

The best care for every hair type

Each hair type has specific needs. Here are care tips for each one:

Straight hair

• Use light shampoos to avoid weighing it down.
• Leave-in conditioners can add volume and make detangling easier.
• Avoid heavy products that can make hair greasy and flat.

Wavy hair

• Anti-frizz products help keep waves defined and smooth.
• Use light mousses to add volume without weighing hair down.
• Avoid products that are too heavy and can flatten waves.

Curly hair

• Hydrate regularly to avoid frizz and keep curls well defined.
• Defining gels or creams help keep curls in place all day.
• Avoid over-brushing curls so you don't break them.

Coily hair

• Hydration is essential; use hair oils and butters to nourish deeply.
• Protect your hair at night with a satin bonnet or a silk pillowcase to reduce friction.
• Avoid alcohol-based products that can dry hair out further: to scent your hair, choose an alcohol-free scented hair mist instead.

Understanding common problems

Some people may have oily hair, while others may have dry, damaged hair. Here's how to recognise and treat these problems:

Oily hair

Oily hair can be caused by the scalp overproducing sebum. To treat oily hair:

• Use shampoos designed for oily hair that help regulate sebum production.
• Avoid heavy products such as thick oils and creams.
• Wash your hair regularly, but not too often, to avoid stimulating sebum production even more.

Dry and damaged hair

Dry, damaged hair lacks hydration and can be caused by chemical treatments, excessive heat or environmental conditions.

• Use hydrating shampoos and conditioners that nourish deeply.
• Avoid heated tools or use heat protectants to reduce damage.
• Hydrate your hair regularly with masks and nourishing treatments.

THE SCIENCE BEHIND HAIR TYPES

Studies and science

The texture and shape of your hair are determined by several factors, including genetics and the structure of the hair shaft. Studies show that the shape of your hair follicles strongly influences your hair type.

The role of genetics

Researchers such as Dr Rolanda Wilkerson have found that the shape of hair follicles is genetically programmed. Round follicles produce straight hair, while oval follicles produce curly hair.

The impact of the environment

Environment and hair care habits also play a crucial role. Frequent use of chemicals, heat and climatic conditions can alter the natural texture of the hair.

Understanding your hair type is the key to a successful hair routine. By using the right products and following tailored advice, you can improve the look and health of your hair. Remember, every hair type is unique and needs specific care to shine.
