Achieving consistent hair styling results is based on the application of controlled thermal energy. The ghd (Good Hair Day) brand takes a specific approach to this: maintaining a constant styling temperature of 185°C. This temperature is considered the optimal threshold for effectively reshaping the hair's structure without reaching the higher temperatures that cause irreversible damage. This article analyses the technical features of select ghd products and evaluates them within the context of various user requirements.
The selection of a suitable heat styling tool should be based on an analysis of your hair's texture and your desired styling outcome. The following parameters are of key importance.
The fundamental choice is between a straightener (styler) and a hot brush.
ghd's core technology is the maintenance of a constant operating temperature of 185°C. Models like the ghd Gold Styler use dual-zone technology. This involves two heat sensors per plate monitoring the temperature to ensure even heat distribution from root to tip. This precise control is a key factor in protecting hair from potential heat damage caused by temperature fluctuations.
The styling plates are typically made of ceramic or feature a ceramic coating. This material is distinguished by its highly uniform heat conductivity and smooth surface. This allows the plates to glide through the hair with minimal resistance, reducing mechanical stress and counteracting frizz. Floating (spring-loaded) plates, found in many ghd stylers, adapt to pressure and ensure constant contact with the hair strand.
Even at the optimal styling temperature of 185°C, applying a heat protectant spray is a fundamental step. Such a product forms a protective barrier on the hair's surface. This barrier helps to lock in moisture and distribute heat more evenly. This reduces thermal stress on individual hair fibres and supports the longevity of the style.
Based on technical specifications and areas of application, we present a selection of ghd products.
While ghd focuses on high-performance styling tools, a comprehensive hair care and protection routine can also include accessories for cold days. For options that protect your head and hair from the elements, you might consider our selection of head warmers.
1. Why does ghd use a fixed temperature of 185°C? According to ghd's research, 185°C is the temperature at which hair can be effectively and lastingly reshaped without exceeding its glass transition temperature. Above this threshold, irreversible damage to the hair's structure can occur. The constant temperature aims to strike a balance between styling effectiveness and hair protection.
2. Can I also create curls with a ghd straightener? Yes. The rounded barrel of ghd stylers, like the ghd Gold Styler, is specifically designed for this purpose. By wrapping a strand of hair around the closed and rotated tool and slowly pulling it through, you can form curls and waves.
3. Is a hot brush gentler on the hair than a straightener? Both types of tools operate at the same temperature of 185°C. The difference lies in the method of heat transfer. A straightener applies direct pressure and concentrated heat, leading to a more intense reshaping. A hot brush distributes heat less directly and over a larger area, which can be perceived as less intense. Correct usage and the mandatory application of a heat protectant spray are crucial for both tools to minimise stress on the hair.
