No, you cannot wear lipstick during Umrah while in the state of Ihram.
During Umrah, specifically when in the state of Ihram (a state of consecration), certain restrictions apply to both men and women. These restrictions are meant to promote humility and focus on spiritual devotion.
According to specified regulations, women in Ihram are forbidden from wearing perfume or applying makeup. This restriction includes lipstick, as it falls under the category of makeup. Adorning oneself with cosmetics is against the spirit of simplicity and purity that Ihram embodies.
Therefore, to adhere to the rules of Ihram, avoid wearing lipstick or any other makeup.
