The colour of your eyes and skin must figure into what works well for hair colour. Individuals who have hazel eyes fit into two broad categories. Some have colouring referred to by aestheticians as fitting into the "warm" season, and some fit into the "cool" season. All individuals look good in specific shades of hair colouring and clothing matching their season. Those having hazel eyes with brown and gold flecks in the iris fit into the warm season. If you have hazel eyes with white, grey or blue flecks, this puts you in the cool season.
Hazel eyes in warm season
Enhancing hair colour enlivens almost any individual. Those with hazel eyes in the warm season look best in hair shades involving reddish highlights and rich golden shades. Avoid extreme shades such as white, platinum, or black. Your skin in the warm season has peach or gold undertones. Your hair colouring should look "sunny" and literally warm in tone. Pale auburn, light golden brown and golden blonde look good with your hazel eyes.
Hair colour for cool season
Hazel eyes fitting the cool season means your cheeks have no colour or pink undertones. Choose hair colour that doesn't have gold, yellow, red and bronze tones. These tones will make you look sallow and drawn. Choose light ash brown, ash blonde or platinum blond to harmonize with your light skin. Select hair colours that are soft and subdued. If your skin has enough colour, you can wear chestnut brown or black. Pale skin and hazel eyes in the cool season with grey, white or blue flecks look best with a delicate shade that has no sunny-looking highlights.
Experiment with semi-permanent colour
You can't bleach your hair with semi-permanent hair colour. You can only go darker. It only lasts for a few weeks, but you can remove most of it by extra shampooing if it's too dark. It's best to colour your hair only one or two shades darker to see if it enhances your look. Permanent colour can lighten the hair to any shade of blonde or light brown. If you bleach your hair or want red or golden highlights, it's best to pay a professional.
Fixing colour mistakes
Naturally warm people do not look good in trendier hair colours on the wild side. Do not use blues, violets, or jet black dyes if you are in this season. These colours will give you a corpse-like appearance. If your hair turns out too dark with permanent colour you do at home, it will take a long time to correct it. No beautician case quickly fix bad colouring mistakes. Always save the box if you colour yourself. A beautician must know what chemicals you used, or a professional correction can make colour worse.
Strive for a healthy glow
If your hazel eyes and pale skin make you look washed out, ask a colourist to help you choose hair shades even if you colour at home. Makeup and clothes do factor into the look, but hair colour is crucial. It's wise to pay for foiling, streaking and highlighting at a salon. You want to use colour in ways that make you look vibrant and alive. The wrong shade of hair colour can make you look tired.
