Short, medium or long – how keratin benefits your hair at every length

Chances are you’ve heard of keratin and just how beneficial it is for hair – but if not, let us give you an insight. Keratin is a protein that makes up the structure of each strand of hair. It’s an essential element for strong, healthy-looking locks, but daily life – things such as excessive heat styling, coloring and bleaching – can cause damage and protein loss in the hair, leading to frizz, dryness and unmanageability.

That’s where using keratin products comes in: when applied in the form of keratin-infused shampoos, conditioners and masques, the hair cuticle absorbs this essential protein to repair hair, making it look and feel smoother, glossier and full of life. It’s an ingredient that’s especially ideal for those with curly hair or if you need help making it straighter, less frizzy and easier to style. The good news is, it doesn’t matter how long or short your hair is; there are so many benefits to using keratin-based products, such as the Nexxus Keraphix Keratin range, on short, mid-length and long hair. Here’s why…

The benefits of keratin for short hair

It’s common to assume using keratin benefits those with longer hair the most. But actually, its versatility means those with short hair will see great results from adding keratin-infused products to their daily hair care routine, too. Those with short hair will know that cropped styles often require a good deal of effort – there’s no throwing hair up in a messy bun or top knot when you’re in a rush. It’s also harder to disguise if you’ve skipped a wash, meaning you often need to shampoo it more regularly. That all means more washing, styling and – potentially – more damage to hair. Those with short hair would benefit from incorporating a keratin-infused shampoo, such as Nexxus Keraphix Damage-Healing Shampoo, to help strengthen hair and protect it against damage from any extra washing and heat styling. It will also make hair feel more manageable and easier to work with; perfect for those days when you’re in a hurry but can’t just throw your hair up and go.

The benefits of keratin for mid-length hair

If you have mid-length hair, keratin is a great ingredient to add to your arsenal. Not only will it help make your strands look incredibly smooth and shiny, but it’ll also help to reduce the appearance of split ends to keep your cut looking fresher for longer. It’s also ideal if your mid-length hair is a temporary thing: when you’re trying to grow your hair longer, using a keratin-infused shampoo and conditioner regularly can really help the look and feel of hair during the process. The Nexxus Keraphix range includes the PROTEINFUSION blend with Keratin protein, which works to help strengthen hair by preventing the ends from breaking. This means it can help keep hair stronger and healthier as it grows.

The benefits of keratin for long hair

Long hair really benefits from using keratin-infused products – mostly because the longer strands are, the more care they need to stay healthy and glossy. By using products formulated with keratin, hair will become smoother and easier to brush through, and – what might be the most appealing benefit to those with long hair – your overall drying time will likely be cut down, too. Why? Keratin protein works to fill in any porous gaps in hair strands, so it holds onto less water. Keratin-infused products are also especially good if your hair is long and curly – Nexxus’s Curl Define Leave In Conditioner replenishes and locks in moisture to control frizz, and the PROTEINFUSION complex (a blend with keratin, silk protein and marula oil) will soften and define curls. This can also be used in-between wash days as a curl refresher, which will help improve the overall health and appearance of curls without the wear and tear of a full wash and style.

Another keratin-packed product is the Keraphix Repair & Strengthen Reparative Treatment, which can be used either as pre-wash boost or a post-shower leave-in. It’s an incredibly versatile re-bonding treatment, especially helpful for long locks that are in need of a little love. Infused with a bonding technology that’s designed to strengthen hair, it provides heat protection, smooths strands and even seals up to 94% of split ends for visible softness and shine.
