From heat styling, over washing and chemical treatments to stress, poor diet, and even the weather, our hair is under constant attack. Excessive blow-drying, straightening, and curling can weaken the hair’s protein structure, making it dry and brittle. Over-washing and using harsh shampoos strip the scalp of its natural oils, leading to frizz, breakage, and dullness. UV exposure and pollution can degrade keratin, the cornerstone of healthy hair. If your locks feel weak, frizzy or easily broken, then it may be down to hair damage. But the good news is that damaged hair needn’t be a lost cause. Here’s a comprehensive guide to hair repair that can restore strength, shine and vitality.
Nourishing Hair From The Inside

The road to hair repair starts at the root. If you’re not getting adequate nutrients and key hair vitamins, then it’s a recipe for brittle, lifeless strands and shedding. Studies show that nutritional deficiencies, particularly in biotin, zinc, and iron, are linked to hair loss. Good diet is vital, but our manic lives often mean we miss out on these important goodies. One of the easiest ways to remedy this is through targeted supplementation. Hair Gain Hair Capsules and Hair Gummies are packed with a unique blend of hair vitamins and minerals and supercharged with AnaGain™. This is an amazing pea sprout extract proven to reduce hair loss and boost growth by up to 78% over just 12 weeks. Used daily, these superb supplements strengthen hair from within, supporting healthier, stronger and fuller locks.
Beyond supplements, a protein-rich diet is crucial, as hair is primarily composed of keratin, a type of protein. Incorporate foods like eggs, fish, nuts, lean meats and leafy greens into your meals wherever possible. And don’t forget about hydration—drinking enough fluids is an essential part of preventing dryness and brittleness.
Hair Repair - Use The Right Shampoo & Conditioner

The wrong hair products can create and worsen existing damage rather than repairing it. Many shampoos and conditioners contain sulphates and parabens (and often all manner of other chemical nasties). They’ll clean your hair right enough, but they can strip the natural oils of the scalp and hair as well. Rough, dry and frizzy strands often result, together with an itchy, irritated scalp. It’s better to pretend these products don’t exist and switch to a hydrating formula free of harsh chemicals that cleanses without causing any further harm.
To further protect your strands, avoid over-washing. Washing hair too often (especially with hot water) can strip away natural oils, leading to a dry, unbalanced scalp. Stick to 2-3 washes per week and use cooler water to help seal the hair cuticle and retain moisture. Refresh your hair between washes with Hair Gain’s next-gen, aerosol free Peptide Puff™ dry shampoo. It absorbs grease and oil instantly while caring for your hair and scalp.
Reduce Heat & Chemical Damage

Excessive heat styling and chemical treatments such as colouring are among the biggest culprits of hair damage. While we all love a sleek blow-dry or fresh colour, overdoing it can lead to split ends, breakage, and thinning. To stop the damage and begin hair repair, follow these steps.
- Always use a heat protectant before blow-drying, straightening, or curling. Lower the temperature on styling tools—anything over 120°C can start degrading hair proteins.
- Limit bleaching, perming, and chemical treatments, as they weaken the hair structure over time. There are some excellent natural dyes out there that can colour hair beautifully without all the damage caused by commercial dyes.
- Try air-drying whenever possible to give your strands a break. There are some lovely styles for air-dried hair too!
If your hair is already chemically damaged, focus on deep hydration and strengthening treatments to restore lost nutrients.
Hair Repair with Targeted Treatments

For intensive repair, you need to take a holistic approach to cover all angles. Deep-conditioning masks, scalp treatments, and gentle styling techniques work brilliantly in tandem together.
A weekly deep-conditioning treatment is a must for repairing dry, damaged strands. Hair Gain’s Hair Mask is powered by the same mighty AnaGain™ ingredient as our Hair Gummies and Hair Capsules. This intensely hydrating mask also contains Panthenol to condition and moisturise locks, and Phytantriol and Natural Betaine to strengthen hair and provide extra protection against heat damage and colour fading. Easy to use and works in just ten minutes. Use once or twice a week, and build in a regular scalp facial too!

Equally important is scalp health. A well-nourished scalp supports healthy hair growth by providing the ideal environment for follicles to thrive. Hair Gain’s Scalp Foam, is designed to revitalise, nourish and care for the scalp, creating the ideal environment for hair growth and strength. A recent study revealed that using our Scalp Foam and Hair Mask together in a hair health regime reduces hair breakage and fall by up to 60% from the first use*.
Protect Hair from Environmental Damage
External factors like UV rays, pollution, and hard water can make for a challenging environment for our hair health. Over time, these elements weaken the hair shaft, causing dryness and colour fading. Repairing hair means forming (and sticking to!) habits which minimise environmental damage:
-
Wear a hat or use a UV-protectant spray when spending time in the sun.
- Rinse hair after exposure to pollution or chlorine to remove buildup.
-
If you live in a hard water area, the high levels of minerals like calcium and magnesium can accumulate on the hair, decreasing its strength and leaving it dry and dull. Invest in a shower filter to reduce this problem.
- By taking a preventative approach, you can protect your strands from unnecessary stress, keeping them strong and shiny for longer.
