Hi, I need an intervention! I'm 51 and feeling fat and frumpy. Grey hair not helping. Can't really afford highlights/balayage. Dislike the "too dark" look of home dye. Is there anything that would tint the greys but leave my natural hair uncoloured? Do I try and blend in the greys or play up the lights/silver tones? I'm naturally brunette with reddish tones. First picture is front of head, second is the back. As you can see the front is greater than the back. Really hating feeling old and grey! Thanks.
