What it is
ReFa Milk Protein Outbath Treatment Royal is a Japanese leave-in hair treatment, 100g, aimed at heavy damage. Smoothed through damp or dry hair, it uses milk-derived proteins to help replenish the protein that heat, bleach, and color strip away, targeting frizz, waves, and breakage for smoother, sleeker, more manageable hair.
It centers on milk-derived proteins, including lactoferrin, to help replace the protein that damage strips from hair.
It is aimed at five signs of heavy damage: frizz, waviness, color fade, breakage, and scalp dryness.
The Royal line is the higher-repair version, made for hair stressed by bleach, high-tone color, perms, or straightening.

The texture was good, but as other reviews have said, the smell was quite strong! I'm sure people's tastes will differ, but I think it's a bit strong.
I liked the scent so much I bought it again!
It makes my hair super smooth! I have long hair, but it grows so well that a small amount (about 1 pump to 1.5 pumps) is enough. The scent is very sweet, so if you don't like sweet scents, it might not be for you, but the feel is really good, so I recommend it! I don't like sweet scents, so I use this after towel drying, then dry it, and then use another oil at the end, so the lingering scent isn't too bothersome.
I like the white type, so I bought this one, which is a step up. I didn't like the smell and it didn't really suit my hair type, but I learned that just changing the product can make a big difference.
It has a really nice scent, but it's quite strong. I have high-tone hair that has been bleached three times, but it feels like it's moisturizing to a certain extent.
