Removing integrated unit/toppik advice

Hello! I’ve been wearing an integrated hair topper for the past five years but had to get it removed since I moved out of town and the 3 Hour drive was getting to be too much every month— probably impossible once I finally deliver this baby lol

I used toppik for more diffuse thinning to cover in areas and realized it got all over my face and sweater, are there any tips you have for better application? I bought the attachment so we’ll try to use that, but need to use the shaker for more diffuse thinning. Also, any advice on how to make sure clumps don’t form?

If anyone is curious, after wearing the integrated topper for five years, I did develop some traction alopecia at where they had attached it to my hair, so definitely something to keep in mind if it’s something you’re considering !
