After izna member Bang Jeemin identified "frequent brushing" as the secret behind her signature silky, swaying hair, many are wondering if the habit actually improves hair health.
In a recent appearance on a fashion magazine's YouTube channel, Bang Jeemin shared the contents of her bag, revealing several favorite hairbrushes. “Ever since I was young, brushing my hair whenever I looked in the mirror became a habit,” she explained. “That is the secret behind my swishy hair.”
Having turned heads at every performance with her glossy, long, straight hair, Bang Jeemin has sparked growing interest in her routine. But does brushing as often as she does truly help hair quality?
Does Frequent Brushing Improve Hair Appearance?
To an extent, brushing does help hair look its best. It detangles knots and aligns strands, which significantly reduces frizz and flyaways. Furthermore, it helps remove dust, debris, and styling product residue that accumulates throughout the day. Brushing also distributes natural oils from the scalp down the hair shaft, providing a natural shine.

However, experts note that the "method" is far more important than the "frequency." Brushing excessively can create repeated friction, which may lead to split ends or breakage.
Protecting Fragile Strands: Detangle from the Ends
To achieve smooth hair like Bang Jeemin’s, the condition of the hair must be considered before reaching for a brush.
Handle Wet Hair with Care: Hair is at its weakest when wet. Brushing aggressively right after shampooing can lead to severe breakage. If you must detangle wet hair, a wide-tooth comb is a much safer option than a dense brush.
The Upward Method: Rather than brushing from the roots to the tips in one long stroke, it is better to start at the ends. Loosen tangles at the very bottom first and gradually work your way up to the scalp to minimize tension and damage.

Choosing the Right Tool for the Job
The type of brush used can drastically affect the health of your hair:
Paddle Brushes: Ideal for long, straight, or thick hair, these are effective at managing large sections and detangling.
Cushion Brushes: These are excellent for smoothing dry hair, especially those with rounded bristle tips that are gentle on the scalp.
Wide-Tooth Combs: Best used during or after a shower to distribute conditioner or treatment evenly without snapping wet strands.
Fine-Tooth Combs: These are best reserved for precise tasks like creating a part or styling bangs.

Healthy Habits Beyond the Brush
Comprehensive hair care involves a lifestyle of maintenance that extends far beyond the act of brushing. Establishing proper post-shower habits is equally critical for preserving the structural integrity of each strand:
Blot, Don't Rub: When hair is wet, the protective outer layer—the cuticle—swells and becomes highly vulnerable to physical damage. Avoid the common mistake of vigorously rubbing your hair with a towel, as this intense friction can lead to roughened cuticles, chronic frizz, and breakage. Instead, use a soft towel or a microfiber cloth to gently press and blot the moisture out, allowing the hair to dry without unnecessary stress.
Targeted Application of Products: To maintain that "swishy" texture seen with Bang Jeemin, it is essential to apply hair oils, serums, and essences correctly. These products should be concentrated on the mid-lengths and ends, where the hair is oldest and most prone to dryness. Applying heavy oils directly to the scalp can weigh down the hair and lead to a greasy appearance or clogged pores.
Essential Heat Protection: High temperatures from blow dryers, flat irons, or curling wands can strip the hair of its internal moisture, making it brittle and dull over time. If you use heat styling tools frequently, always apply a heat-protectant product first to create a thermal barrier. Furthermore, try to use the lowest effective temperature setting and reduce the frequency of heat application to prevent long-term protein damage within the hair shaft.

Ultimately, the path to healthy-looking hair like Bang Jeemin’s lies in the philosophy of brushing "gently" rather than "often." A brush should be viewed not just as a styling tool, but as a preventative care instrument designed to minimize damage and friction. By building small, consistent habits that respect your hair’s specific condition, you can maintain a vibrant, glossy, and professional appearance every day.
