In Singapore’s style-conscious environment, frequent use of heat-based styling tools is common. However, the high temperatures involved create significant stress on hair fibres, impacting hair health. For those with fine, colour-treated, or naturally delicate Asian hair, the risk of heat damage is even more pronounced.
In this guide, Jonsson Protein reviews the specific mechanisms of thermal stress on hair and provides practical strategies and product suggestions to safeguard your hair’s health while embracing your desired styles. It’ll also share insights gleaned from Jonsson Protein hair care treatment reviews, showcasing how their hydrolyzed protein treatments can strengthen hair against heat damage, creating a healthy environment that promotes healthy hair growth.
How Heat Damage Affects Our Hair
Heat styling induces specific structural changes in hair:
- Protein Degradation: Elevated temperatures break the delicate disulfide bonds within keratin, the primary protein in hair, resulting in weakened strands that are prone to breakage.
- Moisture Depletion: Heat accelerates the evaporation of moisture from the hair cortex, leading to dehydration and increased susceptibility to split ends.
- Cuticle Damage: Thermal stress causes the cuticle, the hair’s outer layer, to lift, resulting in increased porosity, frizz, and a dull appearance.
These processes are particularly damaging to hair that has already undergone chemical treatments or that possesses a naturally fine texture.
How to Minimise Heat Damage from Styling

Fortunately, there are proactive steps that can be taken to protect hair from heat damage:
- Applying Thermal Protectants: These products are specifically formulated to create a thermal barrier between your hair and a heat source, minimising direct heat transfer and preserving moisture levels.
- Controlling Temperature Settings: Opt for lower heat settings on styling tools whenever possible. Gradual warming is also less damaging than a sudden, intense burst of heat.
- Reducing Styling Frequency: Give your hair an occasional break and go natural or try heat-free styling routines.
- Using Good Blow-Drying Practices: Keep the hair dryer moving and use a diffuser to distribute heat evenly. Avoid holding the hair dryer too close to your hair.
- Using Alternative Styling Methods: Experiment with styling techniques that do not require heat such as overnight curls, braiding, rolling, or air-drying to minimise heat exposure.
Protective Products: A Line of Defense
- Thermal Protection Sprays: Look for sprays with ingredients like silicones, hydrolyzed proteins, or humectants to create a protective barrier.
- Serums: Apply a lightweight serum to your hair before heat styling to add moisture and shine.
- Leave-in Conditioners: Apply leave-in conditioners to provide an additional layer of moisture and protection, helping to detangle and smooth hair.
When choosing products, look for ingredients like keratin, argan oil, and panthenol that moisturise and nourish the hair.
Embrace Style Without Sacrifice
Heat styling doesn’t have to be a hair-damaging endeavour. By implementing these protective measures and choosing the right products, you can maintain healthy, vibrant hair while looking just the way you want to.
