This multi-functional brush provides salon-quality results and ions for scalp care and hair care. Its combing sensation allows you to adjust volume and achieve salon-quality results. The brush itself is equipped with negative ions to moisturize your hair, smoothing out the flow and stimulating the scalp, helping to keep it healthy. It comes with two different heads: a soft cushion brush with wide metal pins and a hard cushion brush with long and short nylon pins. It's perfect for morning and evening hair care, scalp refreshment, updos, and on-the-go touch-ups. Its compact size fits in one hand, allowing you to maintain beautiful hair and scalp anytime, anywhere. ◆ For updos and scalp care [Soft Cushion Brush x Wide Metal Pins] The combination of a soft, resilient soft cushion brush and wide metal pins provides just the right amount of elasticity and gentle scalp stimulation with its metal tips. The widely spaced metal pins prevent hair from tangling, making it easy to use for all hair types. While combing, they gently stimulate the scalp, removing dirt and dandruff from the hair and scalp. ◆For volume adjustment and scalp care [Hard cushion brush x long and short nylon pins] The hard cushion brush applies pressure to the scalp easily, and the combination of 1mm long and short nylon pins firmly fits and approaches the hair, scalp, and pores. It applies comfortable tension and neatly arranges hair, making it ideal for volume reduction and volume buildup, as well as scalp care. ◆Negative ions that moisturize hair: Continuously generated negative ions reduce dryness and static electricity, leaving hair smooth and manageable with each comb. ◆Sonic vibration for detangling: Press and hold to turn on and activate "low vibration," or press twice for "high vibration" to choose your preferred intensity. The ultrasonic vibrations generate approximately 7,000 micro-vibrations per minute. Simply apply it to your scalp for a pleasant stimulation while gently detangling your hair. It also has an automatic shut-off function that lasts for approximately 5 minutes, so you won't forget to turn it off. ◆ Detachable and washable brush head. The detachable brush head can be washed with water for hygiene. ◆ Battery-powered (2 AAA alkaline batteries, sold separately) for use anywhere ◆ Gift-friendly packaging. Simple operation and functionality make it easy for anyone to use. The cute packaging makes it a perfect gift.
