Thank you for your post.
After reviewing your photos, I fully understand your concerns that you have voiced. Although, I am not familiar with the standards of your supplier for thin skins, this would not be acceptable with our standards.
The front hairline is not laying flush with the scalp, you can see it is lifted. It also does not have a transitional hairline to give you the appearance of how hair naturally grows out of the scalp. Typically, or at least with the HD Thin Skin the front edge of the system should disappear once applied.
A thin skin is not a breathable base, therefore any liquid cannot escape, such as a breathable lace base. This is why you are experiencing itching when you sweat. The sweat and liquid build up under the skin causing the itchiness. In addition to the skin base not being breathable, itching can be caused when shaved hair begins to grow under the system.
I would NOT recommend using Seabreeze to try and alleviate any itching, as this will only cause irritation to your scalp. If would choose to continue wearing a skin base I would recommend our Protouch No Sweat to help control perspiration, which is applied prior to application. You can find the link below.
In conclusion, if you live an active lifestyle, or have an oily scalp, a lace system may be a better choice for you. Sadly, a thin skin does not have the breath ability that a lace system can offer.
