I have very thick dark eyebrows or I did - one has gone grey in the middle and I hate it!
I can cover it with pencil but it wears off or I can use mascara, but I'd like to know if there is a semi-permanent or permanent product that's safe.
If I leave it snowy white it looks like the middle bit is missing, I'm trying not to be vain, but I am!
I know it says not to, but I always use hairdye on my eyebrows when I dye my hair and I've never had any problem - in fact someone at work commented recently that I always have perfect eyebrows. I just put a little dye on a brush (dye brush or a small toothbrush would probably do) and brush it over my brows. Then clean the area around them and leave for 10-15 mins.
Hair color products are used on eyebrows similarly. When your hair is colored get your brows done too. Usually an extra charge if brows are colored different to hair as it needs extra product.
