A simple guide to understanding the role of protein in hair care

If your hair breaks easily or looks lifeless, it’s only natural to reach for extra care. Protein is key here – it’s the building block of each strand, giving hair its strength and structure. That’s why protein treatments are often the first step when you want to restore resilience and a healthier look.

Think of protein as a plaster filling in tiny cracks: it reduces breakage, strengthens the cuticle and creates a protective layer around the strand. If you often use straighteners or hair dye, your hair will almost certainly need more protein. But don’t overdo it – too much protein can leave hair stiff, dry and prone to snapping.

A protein boost is most helpful when hair feels rough, brittle or lacking elasticity. If your hair is already strong and healthy, an occasional top-up is enough. And remember, protein should always be paired with hydration – that’s the only way to keep hair both strong and supple.
