It’s essential for your hair stylist to assist you in determining the ideal hair length for a seamless, natural appearance. The golden rule to remember is to avoid choosing weft hair significantly longer than your current hair length.

If your hair is too short, blending extremely long genius weft hair can be challenging, leading to a choppy and conspicuous outcome. We’ve all witnessed some hair mishaps, and they’re certainly not a flattering sight.

Please note: We have provided a handy chart to estimate hair length. Keep in mind that curly and wavy hair tend to be 1-2 inches shorter than straight hair of the same stated length. Our chart helps you figure out where your hair will fall on your head. It’ll appear longer if placed towards the nape.


Our weft hair can maintain their quality for 2-3 years or even longer, depending on how frequently you wear them. However, it’s important to note that the more you wash and heat-style your hair, the shorter their longevity. To ensure your Weft Hair stay in optimal condition, please follow these care guidelines:

Preserve Moisture: Periodic deep moisture treatments are recommended to maintain the health and moisture of your hair, especially when heat styling. 

Heat Protectant: Always use a heat protectant when styling to prevent split ends, as hair can naturally experience this issue over time.

Difference in Color: Keep in mind that darker colors tend to have a longer lifespan and may have a slightly different texture compared to colors that require more lightening during processing.

Bleaching Restriction: Stick to semi-permanent hair colors and avoid using high levels of developer. Bleaching weft hair is not advisable.

Restricted Products: Avoid using sunscreen and tanning products, as they can cause discoloration. If necessary, opt for mineral-based products when wearing your hair.
