However, you are not alone in your purchase and you can be advised on colour, base size and length based on your photos by sending them via the support form. After ordering the topper, you can then try it on at home and send it back if it doesn't suit you, respecting the 14-day withdrawal period.

You should choose the Cap size of the topper according to the extent of your alopecia and the density of hair you wish to acquire. It is preferable that the clips are not attached in the area of alopecia where the scalp can be quite sensitive. In addition, extensive alopecia will require the addition of a high density of hair to compensate for the initial low density.

For extensive alopecia, we recommend bases measuring 18 × 18 cm or 20 × 20 cm. These bases will provide effective coverage, density, and comfort. Larger bases are available for very extensive alopecia.

Smaller bases (15×15 cm) will give your hair a little less density. But they will make it easier to tie your hair up in a high ponytail.

To determine your wig size, please refer to the chart below.

We offer hair toppers with a density between 120 and 130%. This density is considered standard by international retailers.

The hair is straight. Except when it is indicated in the product description and title that the model is naturally wavy or curly.

The life span of a topper will partly depend on how well it is cared for. The typical life span is between one and two years. To increase the life of your topper, you should not wash it too frequently.

The topper should be brushed out carefully after wearing. It is convenient to place it on a wig head. This way, the hair does not get a bad fold before the next use.

Hair should not be washed too frequently. Every 4 weeks or more is a good frequency. Close the clips before washing the hair and detangle the hair before and after washing. You can use a mild shampoo for colored hair followed by conditioner. Orchid Oil shampoo and Brazilian Keratin conditioner have proven to be effective!

Every four shampoos, you can apply Silicon Mix, available on Amazon. This will restore your hair's original shine.

If you have dry ends, we recommend adding a little argan oil to moisturize the hair fiber.

Natural hair can be heated, straightened, and curled without any problems. However, as with your own hair, you should not overdo it so as not to damage the hair fiber.
