"When I first started using this, I was so pleased with all the new baby hairs that I could see growing. I was also using another product and didn't think I needed this anymore so I stopped. I was so wrong! I've re-started this again and it's taken a few weeks but a fair amount of baby hairs are starting to sprout again. This is definitely a keeper, especially for the price!" — Juju.

"I've been using this product for two weeks now and can already see a massive difference in hair fall. I use it daily at night before going to bed on a dry scalp and massage it in a bit. I wake up with a massive reduction in my hair fall the next day, definitely worth trying!" — SB.

Davines NATURAL TECH Energizing Superactive Serum customer review:

"Over the last few months, I had noticed my hair thinning dramatically, with so much hair fall that it was concerning. I have now been using this Energizing Superactive Serum every week for a month along with shampoo and conditioner from the same range and happy to report that it started to work after the second wash and now has accumulative effects. My hairdresser and I have noted less hair fall each week and my scalp has a restored healthy colour, with no redness and itchy dry feeling it had previously to using the product(s). I would definitely recommend this product — it is superior to the large volume of products I've tried." — Ruby Red.
