Works right away
Scent: Purple
Perfect for wanting your blonde to be on the white side and not yellowish or brassy look. Great of upkeep in-between salon visits. Hair feels moisturized after and soft. BE CAREFUL as this does STAIN your hands and white in the shower / bath. Rinse it off your hands immediately. Bleach will remove any drops or drips. Has a ton. of pigment in it so everything must be throughly rinsed. (no need to freak out first time but it is a bit messy so be prepared but results worth it)

Great products
The Ordinary Serum Favorites Set is a great way to try some of the brand’s most popular products without committing to full sizes. Each serum feels lightweight and absorbs quickly, making it easy to layer into a routine. I noticed my skin looked smoother and more balanced after a couple of weeks of use. The simple, no-frills formulas are effective and perfect for anyone who wants targeted skincare without the high price tag. Overall, a smart and budget-friendly starter set

Quality products that really work
Very happy with The Ordinary products. My skin is glowing, smooth and my pores are smaller. They are easy to use and a little goes a long way. This is a great starter pack if you are wanting to try the line.

No unsafe ingredients
I always love this brand. Their products are amazing quality for skin improvement. As an esthetician student learning about the dangers of certain ingredients, with this brand I don't have to worry about that.
