Is Your Hair Protected This Summer? Why Mediceuticals Defend Is Our Go-To Leave-In Conditioner

We’ve had some glorious sunshine lately – blue skies, warm breezes, and the perfect excuse for beach days or long walks in the sun. But while you’re layering on the SPF for your skin, here’s a gentle reminder: don’t forget your hair.

Hot weather, UV rays, saltwater and even city pollution can all strip moisture from the hair and leave it dry, frizzy or brittle. That’s why we’re big fans of Mediceuticals Defend Leave-In Conditioner – especially in the summer months.

Here’s why it earns a permanent place in our beach bags (and why it might be a great fit for yours too):

Why Leave-in Conditioner Matters in Summer

Leave-in conditioners are a brilliant way to protect the hair throughout the day – not just after you wash it. Unlike traditional rinse-out conditioners, leave-ins stay on the hair to help:

  • Seal in moisture

  • Protect against sun and heat damage

  • Tame frizz and flyaways

  • Improve manageability and shine

Defend does all this without weighing the hair down, making it ideal for daily use – even on fine or thinning hair.

Defend’s Standout Ingredients

It’s not just a quick fix – Defend is packed with clinically backed ingredients that actively work to treat damaged and frizzy hair over time:

  • Provitamin B5 (Panthenol)
    A gentle yet powerful detangler that also improves the feel and appearance of damaged hair by boosting suppleness and shine.

  • Hydrolyzed Keratin
    A protein fragment that penetrates the hair shaft to fill in microscopic gaps, strengthening the structure, increasing moisture retention and reducing frizz.

  • Hydrolyzed Wheat Protein
    Ideal for fine or thinning hair, this protein thickens, strengthens, and adds volume while deeply penetrating and nourishing the inner fibres of the hair.

These ingredients are especially helpful if your hair has been exposed to heat styling, colouring, or environmental stress.

How to Use Defend

Using Defend is wonderfully simple – just spray onto damp hair after washing, focusing on mid-lengths and ends. Comb through and style as usual. No need to rinse.

You can also lightly mist it onto dry hair before sun exposure or heat styling to top up protection. It’s non-greasy, colour-safe, and gentle enough for sensitive scalps too.

And the best bit? It’s the perfect size to pop in your handbag or beach bag, so you can use it on the go whenever your hair needs a refresh
