It is a product I use often for home care . Been using the small ampoule bottle version and purchased the large version this time. 

The large version comes down cheaper to use each time and allows easier amount adjustment. 

Since I need to mix it 1:1 with water I used the small ampoule bottle as measurement. 

My hair was so frizzy but after using this for once a week. After doing this my hair became so soft. I really recommend this product!
