Hair care technologies are advanced solutions aimed at treating various hair problems and improving its appearance and health in an effective and safe manner. These technologies include a range of specialized treatments such as plasma (PRP) injections and mesotherapy to stimulate hair growth and strengthen follicles, along with cold laser therapy to improve blood circulation in the scalp. Protein, keratin, and nanoprotein hair straightening techniques also provide effective solutions for smoothing hair, repairing damage, and restoring its natural shine. These technologies achieve noticeable results in reducing hair loss, increasing density, and improving hair quality from roots to tips.
