Squeezing lemon juice onto your strands and sitting in the sun for prolonged periods is said to lighten your locks. Chances are, however, that you won鈥檛 see any obvious changes. Another drawback? Dryness. If you want to bring out your natural highlights without dye, consider a color-depositing shampoo.Lemon juice in the hair questions?
