The Clairol Natural Instincts 5R Medium Auburn is a semi-permanent hair dye that offers a rich, vibrant color with a warm, red undertone. The 5R shade specifically is a medium auburn, which combines red and brown hues to create a natural, fiery tone that's perfect for those looking to add warmth and dimension to their hair without committing to a permanent color.

Since it's a semi-permanent dye, Natural Instincts is designed to gradually fade over time (usually after about 28 washes), making it a great choice if you want to experiment with a new color or add depth to your hair without the long-term commitment of permanent color. The formula is also typically more gentle on hair, as it’s ammonia-free and often contains nourishing ingredients like aloe, vitamins, and antioxidants to help keep your hair soft and shiny.

If you're looking for a medium auburn color that adds some warmth and richness to your natural hair, this could be a perfect option!
