What's the difference between the trind keratin products and the trind balsam treatments and nail repair? aren't they both for dry brittle nails?

Hello,The Keratin Restorer is a strengthener and the protector a sealant also with keratin. This is because the Restorer is absorbed by the nail. It does not dry with a glossy finish like the nail repair. Therefore, you can use the Keratin Protector to get that glossy finish while also adding extra Keratin. The balsam treatments are strictly for additional hydration. The Nail Balsam adds additional moisture to the nails for extra flexibility. The cuticle balsam hydrates all three layers of the cuticles so nails do not grow in with ridges. The balsams for extra nice nails are used with the keratin products or the Nail Repair.

Was this done everyday?

No. I love all Trind products, but I could not do this everyday. Since it wears like iron, I didnt need to, but it depends on the condition of your nails, I think.
