I am not a believer of the 3 month rule. I have hair systems years old that I still could wear. To me what makes a good hair system is pretty simple . This is in no particular order.

1. The materials used - Light, very invisible materials that feel comfortable and look the most invisible. There are a lot of different laces out there, but when you get a really good one it makes a difference

2. how they ventilate it. Having the right hair direction in spots and venting the hairline to look the most natural. I think ventilation makes a huge part of what can make a hair system crappy, good or fantastic.

3. Following instructions.. how it fits your head, making it right to spec, matching the color perfectly bleaching the knots.. giving you the right density t hat you want.

4. Hair quality. Having better hair quality looks and feels better.

5. Getting your order on time without waiting a long time

6. Price point

If any company can satisfy all of these requirements than its a pretty perfect hair system in my opinion.
