I have naturally dark brown hair and get a high balayage every 5-6 months. While it grows I try to cover the greys at the roots (not a huge amount but I’m late 40s so enough to be noticeable). Have used a Nice and Easy for years but now finding it barely lasts a fortnight (washing hair every 3-4 days so max 5 washes in that time). Needs to be semi/demi rather than perm so that it doesn’t cause issues when bleached later on.
Anyone found one with decent longevity?
