When it comes to achieving glossy, smooth, and resilient hair, keratin and collagen are two powerhouse ingredients that dominate the beauty industry. But while both play crucial roles in maintaining hair health, they work in remarkably different ways. Understanding their differences helps you make an informed decision about which product best suits your hair’s unique needs.
In this detailed guide, we’ll explore what keratin and collagen really are, how each benefits your hair, and the top-rated keratin and collagen hair products available in Kenya at Pharmily Kenya.
Keratin is a natural structural protein that makes up about 90% of your hair, nails, and skin. It acts as a protective shield against external damage such as pollution, UV rays, and heat styling. When your hair loses keratin due to over-processing or environmental stress, it becomes frizzy, dry, and prone to breakage.
Keratin hair products work by replenishing this lost protein and creating a smooth, glossy surface around each hair strand. Regular use helps repair damage, reduce frizz, and enhance the overall manageability of your hair. Treatments such as keratin-infused shampoos, conditioners, and masks can dramatically transform dull, lifeless hair into sleek, salon-perfect strands.
For best results, opt for formaldehyde-free keratin products that strengthen hair without harsh chemicals.
Collagen is another vital protein found abundantly in your skin, connective tissues, and scalp. It plays a significant role in maintaining elasticity, hydration, and strength. In hair care, collagen works more from within the scalp, helping to improve hair follicle health and boost natural growth.
Unlike keratin, collagen doesn’t directly smoothen the hair shaft. Instead, it supports the structure beneath—keeping your scalp nourished and hair strands resilient. Collagen also helps fight the visible signs of aging such as thinning hair and dullness by promoting stronger, fuller, and more youthful-looking hair.
Many collagen hair products today combine marine collagen with vitamins and essential oils, making them ideal for those struggling with hair loss or weak hair strands.
Keratin and collagen offer a plethora of benefits for various aspects of our body, including the skin, hair, nails, and joints. Let's explore how these essential proteins contribute to our overall health and beauty:
The choice between keratin and collagen hair products depends on your specific hair concerns:
Always follow with a heat protectant spray if you style your hair frequently, and choose sulfate-free formulas to maintain your results longer.
The consequences of these differences between collagen vs. keratin are multiple when looking at hair care applications.
On the one hand, low collagen concentrations can make hair appear lifeless and brittle, as well as making it potentially more prone to breakage and hair loss. As such, hydrolyzed collagen is incorporated into hair care treatments in order to assist in rebuilding the hair’s lost protein. This, in turn, can have an impact on hair that is healthier, presents longer growth periods and looks fuller.
Just like argan oil, collagen is an excellent choice to promote healthy moisture levels so that strength and elasticity are maintained.
Keratin, on the other hand, is critical for the structural components in hair. Its role in protecting the cuticle and the hair’s inner core means that keratin depletion (caused by heat damage, chemicals or other environmental factors) might lead to dull, dry or frizzy hair.
Through incorporating keratin hair care treatments, it’s possible to fill in keratin cracks along damaged areas in the hair shaft. This means the products work to heal hair from inside out, while also coating the outer layer of hair, forming a shield. The result is hair that recovers lost luster and shine, while increasing healthy moisture levels.
At Pharmily Kenya, you can find a curated selection of authentic keratin and collagen hair care products designed to suit various hair types and budgets. Here are some of the most popular picks:
A powerhouse formula enriched with keratin that repairs five signs of damage—split ends, roughness, dullness, dehydration, and weakness. Perfect for over-processed hair in need of deep repair.
This duo smooths frizz and strengthens strands with every wash. It’s infused with keratin proteins and argan oil for long-lasting softness and protection.
A dietary supplement that supports natural collagen production, improving hair elasticity and overall scalp health from within.
Ideal for thin or fine hair, this shampoo combines biotin, collagen, and vitamin B7 to enhance volume and thickness without weighing your hair down.
This is a premium source of hydrolyzed collagen peptides, a protein that is essential for the structure and function of connective tissues throughout the body. Collagen is abundant in the skin, hair, nails, and joints. As we age, our natural collagen production declines, leading to decreased skin elasticity, wrinkles, and joint discomfort.
Both keratin and collagen hair products play unique roles in achieving stronger, shinier, and healthier hair. While keratin works to repair and smooth your strands, collagen nourishes and strengthens them from within. Whether you’re battling frizz, thinning, or dullness, combining both in your routine can help you achieve a balanced, salon-worthy glow.
