Let's keep this nice and short.
No, you should not feel embarrassed about having grey hairs. Going grey is a normal part of the ageing process and is something that happens to everyone eventually. There is no need to be ashamed or embarrassed about it.
In fact, grey hair is a sign of wisdom, experience, and maturity. Many people choose to embrace their grey hair as a symbol of their life journey and as a way of embracing their true self.
It's important to remember that hair colour is just one aspect of who you are, and it doesn't define you’re worth or value as a person. Embrace your grey hair, and focus on the things that truly matter in life. You'll find that the more confident you are in your appearance, the more confident and comfortable you'll feel in all areas of your life.
