What is Keratin?

Keratin is a fibrous structural protein that occurs naturally in hair, skin, and nails. It plays a critical role in keeping your hair strong, elastic, and damage-resistant. It has a unique composition and structure that enables it to provide protective reinforcement to the strands of your hair.

Specifically, hair keratin is alpha keratin and has a helical molecular structure that forms lengthy protein chains. These chains twist together to make sturdy strands that provide structure, strength, and flexibility. This gives each hair strand its smooth, bright, and robust qualities from within the cortex outwards.

Research has also shown that incorporating supplemental keratin into hair care products and treatments can help restore hair health. Keratin treatments at salons often use a formula with concentrated keratin proteins to fill in gaps and microtears on damaged hair strands. The formula repairs weak areas, protects from additional breakage, locks in moisture, and adds shine.

Over time, environmental factors like sun exposure, heat styling tools, chemical treatments, and dryness can degrade the hair’s natural keratin levels. This causes brittle, frizzy, lackluster locks. Boosting its contents serves to reinforce and rejuvenate dull and damaged hair.

The takeaway? Keratin equals strong, healthy hair. So remember to take good care of your flowing locks and make friends with this power protein for hair that dazzles! Stock up on nourishing hair products and say yes to occasional salon treatments. Your hair will thank you with boosted shine, silkiness, and strength from cuticle to tip.

The Science Behind The Magic

Strengthening at the Root Level

Keratin fortifies your hair starting right at the root within the follicles under your scalp. This protein acts like a personal train

Having optimal levels in your follicles ensures each new hair is infused with durability and resilience from the get-go. This root-level reinforcement prevents future damage like split ends, knots, and breakage further down the hair shaft. It’s why getting enough of it is key for lustrous, flowing tresses that don’t snap or shed excessively when brushing or styling.

Creating a Robust Foundation

In addition to fortifying each strand, it also supports overall hair density and volume. How? By keeping follicles strong to prevent hair miniaturization and loss over time. You see, each hair follicle has its own lifecycle of growth (anagen), regression (catagen), rest (telogen), and shedding (exogen).

Having healthy levels of it helps hair follicles stay in the growing anagen phase longer. This means thicker, fuller hair. However, damage to the scalp and follicles from inflammation, toxins, and dihydrotestosterone (DHT) causes them to prematurely enter the resting and shedding phases. The result is progressive thinning.

That’s where keratin superpowers swoop in! Getting enough of it protects each delicate follicle from the attacks that can shorten its growth lifecycle. This keeps your overall foundation of hair full and fabulously voluminous.

The Benefits For Your Hair

Strength and Protection

Keratin is the ultimate defender for your hair, providing unmatched strength and protection in various critical ways. Its tightly cross-linked structural protein units form a protective barrier around each strand. This shield protects heat by reflecting and diffusing external heat from styling tools. Minimizing direct heat penetration prevents the inner hair cortex from becoming fried and moisture-depleted.

Additionally, it functions internally like a steel infrastructure beam. Its bonded presence integrated within the hair fiber cortex and cuticle layers provides reinforcement durability. This allows keratin-enriched locks to withstand all kinds of daily attacks – from hair brushing, braiding, chlorine damage, UV rays, and repetitive chemical treatments. Its sturdy infrastructure causes these stresses to simply bounce right off, leaving hair smooth and undamaged!

Provides Resilience and Growth

It also nurtures longevity and optimal growth by nourishing hair follicles and strands with vital nutrients. First, it supplies essential amino acids like cysteine, serine, and proline that get transported from the cortex outwards to all layers of the hair fiber. This keeps each structural component – the cuticle, cortex, and medulla – properly nourished to function at its healthiest.

Second, the nutrients in keratin promote faster hair growth cycles. This results in longer lengths between trims, improved thickness across the scalp, and enhanced overall density. Fostering resilience against breakage allows existing strands to reach longer maximum lengths before shedding. Damaged strands also benefit from its reparative nutrients, rebuilding areas of overprocessing from chemicals or environmental factors.

Prevents Hair Breakage

Finally, it acts like an adhesive glue reinforcing and binding cells together for improved structural integrity. Its bonded presence throughout the hair fiber lends a fortifying effect similar to steel rebar reinforcements inside the concrete. This significantly strengthens tensile properties – meaning each strand can withstand more tension, friction, and manipulation without cracking or breaking along the length.

With sufficient keratin reinforcement, hair stays resilient when brushed, blown dry, flat ironed, curled, or styled. This means visibly silkier, bouncier locks with fewer split ends, fractures, and breakage issues. Get your fill of this powerhouse protein for enviably strong, happy hair!

Making the Most of Treatments

If you want to incorporate supplemental keratin into your hair health regimen, professional salon treatments offer an ideal option. These intensive conditioning treatments open the outer hair cuticle layer with a mild chemical process to allow deeper penetration of the liquefied formula. It then bonds at the inner cortex level before the cuticle closes and hardens to seal it in.

Aim for professional treatments every 3-6 months depending on how quickly your hair loses the infusion. To maximize results, focus treatment only on the damaged lengths and avoid roots that grow out quickly. Complement with shampoos and conditioners in between for ongoing benefits and sheath the strands less frequently when possible to keep more of it intact.

Dos and Don’ts: Ensuring Optimal Results

When using keratin hair products, be patient with processing times as required. Air dry strands thoroughly before heat styling for optimal bonding. Oil roots when heat styling to prevent the newly smoothed strands from drying out. Invest in a hydrating mask or gloss for upkeep. Use treatments only as recommended to avoid overprocessing or damage from overlapping services. Check ingredient lists of all other hair products to ensure they do not strip the levels out when used between treatments.

Above all, resist overprocessing with too many overlapping chemical services! Wait at least 2-3 months after treatments before using hair dye, bleach, perm solutions, or relaxers. This keeps the inner hair structure strong and stable for maximum integrity.
