I was a firm Believer of sfsl hairline front,it was all I’d known
my hair salon ordered me sfsl front , middle,and poly perimeter.
To kinda get the best of both worlds,

Hmmm,im 3 months into wearing my skin hair system,
What I disliked straight away was the uniformity of the hairline,
Seemed to perfect to me,
And generally there is a difference between sfsl, randomness of the hairs,
And skin systems uniformity.

The actual bond always seemed solid with sfsl,

But I’m moving back to sit on the fence,
As the learning curve, bonding my medium skin hairline with orwg has yielded superb results,
Rock solid,

The last few days here in the uk it’s been very clammy, wet forearms tell you it’s goanna be one of those days.
and the hold hasn’t budged.

But aside the bonding between sfsl& skin, which is prop 50-50

I’m thinking the great advantage of skin is no grid pattern,

According to my one lady salon two years ago in October,
Sfsl is so yesterday everyone’s wearing skin nowadays,

Having mentioned all of the above,
The magic formula to hairlines and pieces or cherry’s on the cake
Is the use of product,to give added breakup, texture, shine, protection,
