One of the most famous redheads of our time right now is definitely Julia Roberts. Julia Roberts has come out with so many different red shades. She's done lighter, coppery blond. She's done rich, light coppery auburn shades. Right now, most recently, I see her with deep, rich, rich auburn shades, a little darker than maybe she's been in the past.
This is such a great Julia Roberts look for you to try at home. First what you do is determine if you have a warm skin tone or a cool skin tone. Once you've determined if your skin is warm or cool, you can go shopping for your best red shade. Cooler skin tones stick with cooler reds. Warmer skin tones stick with warmer reds.
In order to get a Julia Roberts current red auburn hair, I would choose a red in the levels 5 or 6. For the first time, if you have natural hair, why not try a semi-permanent shade? A semi-permanent shade will give you the deepness and the richness of the auburn that Julia Roberts has, without all of the maintenance and without all of the regret.
By going with a semi-permanent shade, it gives you the chance to try out a shade just like Julia Roberts, without all of the commitment. It will last for a month or two to let you see if you like it.
If you're looking for a look like Julia Roberts to try at home, I think you should try a semi-permanent. And remember to always check your skin tone against the color box that you buy.
