Hair may seem like a simple strand, but it’s far more complex than meets the eye. From its roots buried in the scalp to its visible ends, your hair’s structure plays a vital role in its growth, health, and appearance. In this blog, we’ll break down the basics of hair structure, explore the hair follicle, and touch on the hair growth cycle. Plus, we’ll recommend some of Cécred’s products that work in harmony with your hair’s natural structure.
What Is Hair Structure?
The structure of hair refers to its physical and biological components, which are responsible for its strength, elasticity, and overall health. Hair is made of keratin, a protein that forms the building blocks of the strand, and its structure is divided into three primary parts: the cuticle, the cortex, and the medulla.
-
Cuticle: The outermost layer of hair that protects the inner layers of the strand and is responsible for shine and smoothness. Keeping the cuticle intact is essential for reducing frizz and retaining moisture.
-
Cortex: The thickest layer of the strand, where most of the hair’s strength, elasticity, and pigment (color) are found. Treatments like Cécred’s Reconstructing Treatment Mask are designed to penetrate the cortex and repair damage from within.
-
Medulla: The innermost layer, present mostly in thicker hair types. While its exact function is less understood, the medulla is thought to contribute to the overall structure, strength, and insulation of the hair. For some hair types, it may be absent altogether without significantly impacting hair health or appearance.

What Is the Structure of the Hair Follicle?
The hair follicle is the part of the hair embedded within your scalp. It’s where the hair grows, receives nutrients, and is anchored in place. The follicle structure includes:
-
The Bulb: Located at the base of the follicle, the bulb is where new hair cells are produced. This area contains living cells and is nourished by blood vessels that provide oxygen and nutrients for growth.
-
The Sebaceous Gland: This gland produces sebum, a natural oil that keeps hair hydrated and protected. However, overproduction of sebum can lead to oily hair, making clarifying products like Cécred’s Clarifying Shampoo & Scalp Scrub important for balance.
-
The Dermal Papilla: A critical component for hair growth, this area connects the follicle to blood vessels and plays a role in the hair growth cycle.
Taking care of your scalp health is essential for maintaining healthy hair. Using scalp-nourishing products like Cécred’s Restoring Hair & Edge Drops can create an environment that supports strong, healthy hair.
What Are the 4 Stages of Hair Growth?
The hair growth cycle consists of four stages, which determine how hair grows, rests, and sheds. These stages are:
-
Anagen (Growth Phase): This is the active growth phase, lasting anywhere from 2 to 7 years, depending on genetics. About 85-90% of the hair on your head is in this phase at any given time.
-
Catagen (Transition Phase): A short, transitional stage lasting about 2-3 weeks. During this phase, hair stops growing, and the follicle begins to shrink.
-
Telogen (Resting Phase): This phase lasts about 3 months, during which the hair remains in place but is no longer actively growing.
-
Exogen (Shedding Phase): The final stage, where old hair is shed to make room for new growth. On average, you lose 50-100 hairs per day during this phase.
Consistent scalp care and strengthening treatments can help support hair during all phases of the growth cycle. Cécred’s Fermented Rice & Rose Protein Ritual strengthens strands and reduces shedding related to breakage, ensuring that your hair retains its length and density.

Now that you know the basics of hair structure, here’s how to care for it:
-
Nourish the Scalp: Healthy hair starts with a healthy scalp. Use products like Cécred’s Restoring Hair & Edge Drops daily to nourish the follicle and visibly fuller looking hair.
-
Strengthen the Cortex: Incorporate deep conditioning treatments, like Cécred’s Moisturizing Deep Conditioner, to deliver moisture and repair to the cortex layer. For more intensive care, try the Reconstructing Treatment Mask, which replaces depleted proteins and targets damage at the structural level.
-
Protect the Cuticle: The cuticle acts as a shield for your hair, so focus on sealing it with Cécred’s Moisture Sealing Lotion to lock in hydration and smooth frizz.
-
Clarify Regularly: To maintain a healthy scalp environment, remove product buildup and excess oils with Cécred’s Clarifying Shampoo & Scalp Scrub.
