Working the keratin protein for hair into your routine

It’s no secret that keratin is an incredible ingredient when it comes to smoothing and taming a variety of different hair types: aside from working wonders on frizzy or unruly hair, it also helps straighten and nourish thick, dry hair, too, infusing strands with all the good stuff they need to keep them looking happy and healthy.

And while you’ve likely heard of keratin, it’s important to understand exactly what keratin is, what it does and why it’s good for your hair. Put simply, keratin is the protein that both hair and nails are made of. In the former, it’s the stuff that works to prevent breakage occurring, frizz from happening, and it can even work to protect against heat damage.

By incorporating keratin into your at-home hair care routine, it can help to smooth, nourish and de-frizz. You’ve probably heard of the in-salon treatments available, during which a professional-strength keratin treatment is applied to hair with results promising to last around six months or so. But there are also a whole host of ways you can include the powerhouse ingredient at home, without having to trek to the salon.

So, if you’re looking for the tips, tricks and products that can help you maximize the keratin levels in your locks, look no further.

Is keratin a Treatment?

What is keratin? Keratin is a type of protein that maintains the health and structure of our hair, skin, and fingernails.

The benefits of using keratin shampoo and conditioner

Probably the easiest way to incorporate keratin into your own hair routine is by using a shampoo infused with it every time you wash. Nexxus’s Keraphix Damage Healing Shampoo contains a blend of keratin protein and black rice, an age-old ingredient that was originally designed to heal the visible signs of hair damage. Using it each time you wash means you’re able to reinvigorate locks time and time again, with zero extra effort needed.

Why keratin protein conditioner is a must-use

Of course, we all know that conditioner is a non-negotiable when it comes to ensuring hair remains looking and feeling as healthy as possible. But, add a dose of keratin into the mix and you’re onto a serious winner, especially if hair is feeling dry, damaged or looks frizzy. Like the shampoo in the same range, Nexxus’s Keraphix Damage Healing Conditioner is infused with the brand’s signature PROTEINFUSION blend, which uses keratin protein and black rice to nourish and soften hair, making it more resilient. The clever formula is able to penetrate deep into the hair fiber, helping to repair it from within for a smoother-than-ever look and feel.

When to use a keratin deep conditioner

If your hair feels like it’s on the drier, more frizzy side, but it’s not quite in need of a full-blown at-home treatment, it might be a good time to switch out your regular conditioner for a keratin-infused masque. A product that sits somewhere in the middle, it’ll nourish and restore hair almost instantly but isn’t as intensive – or as time consuming – as a treatment. As part of the Nexxus Keraphix range comes the masque for damaged hair. Use the full sachet whenever hair feels a little parched and unloved, to restore it to its former visibly stronger, healthier glory.

Are at-home keratin smoothing treatments worth doing?

In short, yes. Of course there’s no denying that an in-salon treatment will last longer than any of the DIY ones, and they’re especially useful if your hair is the victim of heat styling, severe chemical damage or coloring. And believe us when we tell you that Nexxus’s Keraphix Repair & Strengthen Reparative Treatment is the next best thing if you’d rather get results from the comfort of your own bathroom. Rest assured, though, because this treatment is a leave-in product that has been salon-crafted and has ingredients to leave hair silky smooth with improved elasticity. It can also be used as a pre-wash treatment, making it even more versatile.
