Made My Hair Soft and Bouncy
Gifted by nutrafol. I see Nutraol everywhere—TV, my dermatologist's office, TikTok—I was very eager to try this! I have fine hair that has thinned out significantly since having two kids. My hair is also dry and lacks shine. Pretty much any products that say they will thicken or moisturize weigh dow...

I would not recommend
I have very thin, fine hair. I've been losing more and more it seems over the past 6 months. I read great reviews about Nutrafol and decided to bite the bullet. Boy do I regret it! The shampoo is neither great or horrible, average at best. This conditioner though, horrible! I am losing twice as much...

Great conditioner
I received this complimentary from Nutrafol and have been using the matching root purifier shampoo. I really like that it has postbiotics as it's the first time I've ever tried something like that in my haircare routine. I leave it for a few minutes before washing it out. I think it does help prevent my hair from being too dry, which will really help with my fragile, thin hair.
I love it
Since it's called the "Strand Defender," I expect this bottle to defend my hair from my daily heat damage and existential dread. Honestly? It's so lightweight it feels like absolutely nothing, but my hair wakes up looking like a silk waterfall. It doesn't weigh my hair down at all, which is a literal vibe for my fine strands. She's expensive, but if it keeps my hair from snapping every time I brush it, Nutrafol can just take my coins. 10/10, bodyguard approved. gifted by nutrafol complimentary from nutrafol

Soft without being weighed down.
I have always heard great things about Nutrafol, so I was very excited to try this conditioner after struggling with hair thinning. After using this conditioner, I instantly noticed that my hair felt soft without feeling weighed down. My hair seemed stronger, and after blow drying it felt and looked thicker. I can't wait to see my results after using this conditioner over a period of time. Gifted by Nutrafol.
Amazing conditioner!
This conditioner is a must have! In combination with the Root Purifier shampoo they both give my scalp a spa-like treatment. After washing with the shampoo my hair feels clean and refreshed but not dry, and the Strand Defender conditioner makes my hair so soft and easy to brush through. Together they are a powerful duo! Can't wait to see density and growth results in a few months! Definitely a great pair! Gifted by nutrafol
Doesn't weigh my thin hair down!
This condition that I received complimentary from nutrafol is so good to my hair. I've been using it for a while now and my hair feels so soft every time. I naturally have thin curly hair and this works so well with my hair type. My curls are not weight down at all. My hair feels soft, bouncy and has volume.
