A product I've been using consistently! Healing Bird No-Wash Ampoule Treatment

I sprayed it before drying my hair again today. I love that I can use it without rinsing it off. The scent is exactly to my liking, and I like that my hair gets less tangled and smells subtle, like I've applied perfume. I also love how soft my hair feels when I touch it after drying.
