Try a concealer with a lot of yellow, or just yellow color corrector if you choose to wear make up. Yellow will cancel out the blueish tint from the hair roots. Put your regular foundation over the top.
Sorry if you already know this, but as a ciswoman with a lot facial redness (green for that!) I didn’t learn about color correction until I was well into adulthood. And if it gives anyone a shortcut in their journey I’m happy.
My local is typically closed on Mondays, but opened today.
