A3 Lemon Lightening Serum for Hair Brightening & Sun-Kissed Highlights 50ml/1.69 oz
The 50ml bottle, which is the size to buy once you know the serum works on your hair rather than the size to start with.
A3's lemon serum is a gradual brightener. Real lemon extract, applied and left in, lifting warmth into blonde, light brown and naturally fair hair over repeated use rather than in one dramatic session. The gradual part is the safeguard, since you can look at your hair each week and stop when the tone is right. That is not an option with a box lightener. Where it earns its place is on grown-out highlights: roots aside, the mid-lengths and ends of highlighted hair go dull and slightly muddy after a few months, and a brightening serum refreshes them without another salon appointment.
Hair is left soft and shiny rather than dry, which is the difference between a formulated serum and the lemon-juice-and-sunshine version. Use it on the lengths, keep it off the scalp, and give it time.
