Hi LosingHair,
Thanks for your post. The man bun style can be achieved with a hair system. It's important not to pull the hair back too tightly as
that will put a lot of stress on the base. A day in the sun is tough on all hair--your own growing hair and a hair system--as the sunlight causes the hair to fade. That's how we get the term 'beach boy blonde.' Early on in the life of a hair system it probably wouldn't need to be dyed. Using a shampoo that conains a sunblock will help. You need to read the labels to see if the shampoo contains sunblock. But the sun damage is cumulative and soon you would need to color the hair. 'Back 2 Natural' is a great product for that. If possible it's a good idea to wear a cap if possible as that will protect the hair. Thin skin and lace both have great hairlines. I've worn both skin and lace units and I don't notice any difference in the way the hair behaves. After a few washings they seem the same. And if you're wearing a man bun it doesn't really matter anyhow. You're right about the knotted thin skin being more durable than the injected thin skin since there is more material to 'anchor' the hair. Wearing 7 days with a glue attachemtn is very reasonable. It would take only a medium strenght glue such as Liquid-Tape to achieve that. A stornger glue like Ultra Hold would go about 2 weeks or longer. Looking forward to see pics of your hairline.
Regards,
John
