Hair Anatomy & Structure

What is HAIR?

Media depicts beautiful hair as full, healthy and shiny. But what exactly is hair? Hair is just one part of our complex biological framework. Yet this single anatomical feature is deeply embedded in our identity. Which is why it’s unsettling when we have had bad hair days or worse, when we start losing it. At Daniel Alain, we understand not only the importance of hair health, but how deeply the thread of our hair weaves through our identity, femininity and confidence.

Right now millions of women are seeking answers. Our Hair 360 Center is a sanctuary of solidarity, resources and solutions to guide you.

Whether your hair loss journey is temporary or long-term, we are committed to equipping you with innovative knowledge and resources to empower you to fall in love with your hair again. To do this, we first have to understand the complexities of our hair, how it grows and why for many of us, it falls out. 


There are certain steps we can take to preserve our hair follicles, stimulate growth, prevent hair loss and achieve beautiful, healthy-look hair. Yet even if we take all the right steps to take care of our strands, there are various medical and genetic threats outside our control.

A fundamental of providing solutions is understanding the dynamic issues women face. At the root of our hair health is the anatomy of hair strand and health of our hair follicle structure. With knowledge and understanding, we’re able to stay on top of cutting edge hair science and provide comprehensive solutions.


Given the emphasis on abundant, healthy hair, it might come as a surprise that hair strands are actually lifeless. A closer inspection on hair follicles, however, reveals a cycle of life generated by abundant and very much alive hair cells. These cells conduct crucial biochemical activity in order to regulate the hair growth cycle as part of a complex and delicate ecosystem within the dermal biome.

Within the cycle are four phases: Anagen, Catagen, Telogen and Exogen. At any given point in time, each hair is in a different phase.


Hair grows from the hair follicle and is made of protein cells called keratin. While a strand of hair might seem thin in your hand, it’s comprised of three layers:

1. Cuticle
This is the outer layer of the hair strand which protects the cortex.

2. Cortex
The thickest layer of hair is the inner layer, which is responsible for hair strength, color and pigment, and hair texture. For example: the cortex is the reason why you have blonde, thin hair or red, thick hair, or any combination of hair thickness and color.

3. Medulla
The third and innermost layer is extremely thin and fragile. In fact, it’s nearly invisible and is generally only prevalent in thick, coarse hair. For example, naturally blonde and thin hair do not tend to have the medulla.

How Hair Structure Impacts Hair Health

If the cuticle protects the cortex, ultimately defining the condition and attributes of your hair, and the medulla is only present in thick, coarse hair; how does this relate to your hair health? Imagine the cuticle as your hair’s shield; it’s the first line of defense and outer layer of the hair shaft. Essentially, the cuticle is the cortex’s bodyguard.

Bottom line: the condition of the cuticle impacts the condition of your hair. To have strong, healthy hair relies on having strong, healthy cuticles. How can you improve the cuticle?

The cuticle is made of protein scales that overlap to lock in moisture. The healthiest hair repels water because it has a hydrophobic outer lipid layer. This thin layer is vital to lock in moisture. A closed cuticle keeps moisture in and reflects light which means: hello, shine! Shiny hair isn’t the only benefit of a closed cuticle: it also reduces breakage and friction. 

Porosity & Hair Beauty

We often hear the term, “damaged hair,” but what does that mean exactly? When hair has damage, it happens to the outside cuticle layer. The result is a lifted cuticle with holes, scaling and cracks. These symptoms often accompany the term, “porous hair.”

When hair looks dry or dull, it’s likely due to high hair porosity. When cuticles have trouble retaining moisture, it creates “weathered” hair, meaning it isn’t reflecting light, lacks shine, and may have split ends and breakage. Ready to close the cuticle, lock in moisture and obtain soft, shiny hair? We thought so!

Moisture & Hair Beauty

Craving luxurious, shiny hair? You’re in good company and it’s time to take a hard look at moisture. Maintaining a desired moisture balance is essential to having healthy-looking hair and protecting the integrity of the cuticle. Is the solution as simple as using moisturizing products to restore the cuticle’s ability to repel water and retain moisture? That depends: a moisturizer must either improve or maintain hydration. With this in mind, moisturizers fall into three categories:

These act as a seal by physically preventing water loss so the cuticle can retain moisture.

Moisturizers that attract moisture to the hair and result in softer, more elastic and less brittle hair.

Provide a protective shield that smooths the cuticle and repels moisture. Emollients work effectively when the right proportions are achieved: too much can weigh hair down and make it look thinner., too little creates dehydration, static, and increased frizz.


Suffering from dry or brittle hair? This means that the cuticles may be compromised and you are losing valuable moisture. To achieve the right balance of moisture, Daniel Alain created INTACT, an Anti Hair Shedding Treatment that contains a unique blend of emollients (the protective shield), and humectants (the moisture-attractor). Together, these moisturizing aids maintain the balance of moisture in the hair. And don’t even think about buildup or heavy hair, because the precise blend is strategically designed to create ultimate moisture balance without using silicones, oils or residual building agents.

How? This innovative blend includes rich coconut fatty acids that help the cuticle lay flat. This enables the cuticle to reflect light and ultimately, enhance shine. And that’s not all nature’s moisturizer does; coconut fatty acids are high in lauric acid which due to its low molecular weight can penetrate the hair shaft to nourish, repair and moisturize from within.

Say hello to light, bouncy hair that’s full of body and shine.

Love my Follea Rene - and the amazing customer service!

I considered purchasing a wig for years as my hair became increasingly thin. I finally decided the time was right and I’m so thankful to have found Follea. I purchased the Rene 12 inch in Caramel Latte and I absolutely love it – both the color and style are perfect. Stylist consultant, Tracy Romo, was so incredibly supportive and knowledgeable -- she walked me through every step of the process. She assisted with measurements and answered all of my questions via video calls. I can’t say enough about the amazing customer service I experienced from beginning to end. Tracy guided me in the right direction every step of the way, even sending me helpful videos and styling tips. I honestly couldn’t be happier with my experience.

Easy Beauty!

My Follea Style (6-11) is in all honesty the most comfortable wig I've ever worn - and I hate anything on my head! This wig just... goes where it's supposed to, no pulling it this way or that, no realizing your doggone wig is crooked.. AFTER you walk in to work. This success is in no small part to the Fit Kit I was sent to make sure of my size. 😊

Also, to say the hair is beautiful gives beauty a bad name. The hair is stunning. (I wear color Latte.) My consultant, Ashley, virtually took my hand to guide me through the process of buying my wig. Her help was and still is invaluable.

My hairdresser is very comfortable styling wigs. She created just the right "style" for my Style. That said, even straight from the box, Follea rocks!

Reading your Follea experience warms our hearts, our goal and mission is to help women all over the world feel beautiful, confident and like their best self. Ashley is an amazing and knowlegable guide, that will continue to be with you on your hair journey!

We invite you to join our @Follea community on Instagram, to learn best practices for your new Follea.

Thank you very much!

Wig #6

The ready to wear wig I received from Daniel Alain is beautiful. The packaging was so respectful of the wig. So impressed. I called with questions before purchasing and the staff was very kind and respectful as Loosing my hair was so unexpected and stressful. Thank you for wonderful customer service and a beautiful wig. So many compliments on how it makes me look. Thank you.

We are honored and so glad to hear you had a pleasant experience! Thank you or trusting us to help you during your hair-loss journey.

Thank you !

I had an amazing experience with purchasing a wig with Follea.
I can’t say enough about Tracy and the VIP service I got from her. She was always there on the other side of the phone , no matter what day or time and help me every step of the way!
I have never had such great customer service in any of the other leading wig companies I bought wigs from. Hands down the best!
Thank you

Tracy Romo is a life changer!

When you first go through your personal hair loss journey, you go through so many emotions and sometimes you get desperate. People like to take advantage of those searching for an answer. After making a very costly mistake, Tracy was a game changer for me! She was amazing, very knowledgeable and helped me understand what to look for, how to ensure I got the right size, face timed me to measure and ensure it was correct. I cannot say enough amazing things about Tracy, and my amazing Follea wig.

Kim, Thank you so much for taking the time to share your experience Daniel Alain. It warms our heart to hear to Tracy was such a positive impact. We would love to see your new hair debut, tag us on instagram @Follea.

Style 10 Inch Color 5005 Macchiato (comes with a soft rooting)

This is my first wig but not my first attempt with alternative hair. Its been a journey and one I knew I wanted to take with Follea. I was not wrong. The hair is silky soft and beautifully shiny. The staff is great and wonderful to work with. Their online consultation process is just what I needed. I received sample caps to try on to determine which size is the right size for me. I received color swatches as well to make the color selection process was a breeze. It does make a difference to see to the colors in person, dont be afraid to ask for color swatches. To see them against the light or while your home is worth it. All this happened after the online consultation, which was simple and fun. The rep provided samples of everything, explained the differences with each one. This helped me make a decision on what was right for me. Getting the samples of the wig caps and color swatches was a fun part of the experience but it also made me feel good about my decisions. I often worry about getting the wrong size and color. Once I was set ( and yes I changed my mind a bit) we went forward with the order. After I received my wig and cut the lace, the team was still there to help me with any questions I had.

Overall a great online purchasing experience. Once I received my Follea, I instantly knew this was it for me. I loved it and I was confident to wear it out.

Feeling Myself and Happy with a beautiful Follea Style, 10", Irish Cream

There are no words to fully express how grateful I am for finding Follea and meeting Janet. Her kindness combined with a professional, yet so gentle, advice helped me to find my beautiful natural looking European hair. Janet patiently showed me different styles and sizes (my head is so small!). She has never pushed me to anything. Only offered support and help on the way to my decision, and eventually ordered (incredibly urgently) the right size. I wish all patients to meet someone like Janet on their way! Before I found Follea, I faced a few horrible pushy people who wanted to make money of my sensitive, fragile situation of suddenly losing hair.
Today, I can face the Universe with a smile, again. I am back to work and normal life, interacting with people, attending important business meetings. Letting my health recover in calm confident state.
Thank You to Follea and Janet. May the Blessing and Kindness come back to You Multiplied Million Times.
I am already thinking of ordering a second Follea Style (bit longer this time). Every girl needs a special occasion HAIR! I have found mine.

Follea's Petite

Recently, I bought the Petite in Chai Latte blonde with a natural-looking darker root and customized my piece by adding a few wispy bangs. If you are like me and try to stretch the length of time between washes to prevent an itchy scalp and breakage, this little priceless gem is a quick four clips away from a good hair day.
