@engineermeg: Replying to @Karen ran this like a controlled experiment because that’s the only way my brain lets me trust a result 🧪🥼 13 weeks using the L’Oréal density booster scalp serum while keeping all other products the same so I knew the results were legit 📊 amenexil is actually studied for shedding, which is the whole reason I switched from the Pantene serum 🔄 #hairgrowth #scalpserum #amenexil #hairscience #engineergirl @L’Oréal Paris
