Mini Scalp Applicator: This hair oil applicator allows serums, nutrients, conditioners, and oils to reach the scalp directly. It accurately delivers serums to the roots, preventing them from sitting on the surface of the hair and keeping hair and hands clean. The scalp applicator is designed to be gentle during use to avoid pulling hair. This comb is not suitable for shampoos and other high-viscosity liquids that may not flow properly from the applicator bottle. High Quality: Scalp massage brush made of ABS, silicone, and stainless steel for durability and water resistance. Can be used during hair washing. The comb oil bottle is tightly sealed to prevent spillage or leakage during use. Clean the inside after each use to prevent residue buildup that could block the flow of liquid from the comb teeth. Convenient to Carry: Scalp applicator with built-in 30 ml liquid tank. The compact design helps prevent waste of serum. Press the soft cap to release liquid anytime. The surface features non-slip strips for secure grip. Lightweight and portable for use at home, while traveling, or on trips. Easy to Use: Scalp massaging comb with elastic ball-rowed, curved design featuring 12 elastic ball tips and 7 auxiliary comb teeth for comfortable scalp contact and improved blood circulation. The oil applicator delivers liquid directly to the roots, eliminating manual application. Simply roll the comb across the scalp and press the soft cap to enhance liquid flow and absorption. Multi-functional Scalp Massager: The hair oil comb has a 22 mm wide filling port for easy cleaning and refilling. Suitable for both men and women and all hair types, including thick, thin, curly, straight, wet, or dry. This scalp applicator makes hair and scalp care simple and convenient wherever you are.
