Abbey YungCan the K18 Future IQ Hair Longevity Scalp Serum stop you from going gray forever? Not quite… I’ve seen your requests to review this since it first launched, but because of how complex this category is, I didn’t feel comfortable doing that with more information from K18 directly. In the meantime, I reached out to our favorite chemist over at theskincarebookshelf (on IG) to see what he was able to find out about the patents + specific ingredient complexes used. My call with the K18 science team confirmed everything he shared! I hope this helps to give you the information you need to figure out if this one is worth the $120 splurge for you or not. LMK which haircare product you want me to hunt down answers for next!! #k18 #hairloss #grayhair #scalpserum
