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...

SMELLS STRONG
Gifted by Nutrafol - wow is this strongly scented conditioner! So lemongrassy and overwhelming, I cannot use this regularly unfortunately. Make a fragrance free version and this would be a knockout product!!

Because it's strengthens it hardens hair
Hair Type Very Curly Hair
Loved the shampoo, but the conditioner didn't really work on my extreme curly hair. It didn't really help me detangle so I had to mix it with another but I still don't mind using it because I will reap the benefits of it using the shampoo as well. Gifted by nutrafol
Combats thinning hair
Hair Type Straight Hair
As someone who struggles with thinning hair in my 30s, the Strand Defender Conditioner has been a lifesaver for keeping my hair in my head and not on the shower floor. Plus, I've noticed my hair is overall softer and more volumous since using this on my hair-wash days! I was gifted by nutrafol.
Lightweight and effective
Hair Type Straight Hair
The consistency is lightweight but still creamy enough to coat the hair evenly without weighing it down. It makes detangling so much easier, my brush glides through with barely any effort. After rinsing, my hair feels soft, smooth, and more manageable. Complimentary from Nutrafol

Makes my hair thicker and stronger!
Hair Type Wavy Hair
I'm super impressed with Strand Defender conditioner by Nutrafol. My hair has been thinning so I was exited to try Nutrafol and see for myself. I've been using both shampoo and conditioner and I'm totally hooked. My naturally thin flat hair looks so much thicker, healthier and fuller! Shampoo thoroughly cleansed my hair and conditioner gently hydrated my hair without weighing it down. I'm very pleasantly surprised how good my hair looks now! Also both products have a really nice scent and feel very luxurious. I will definitely repurchase both of them. Gifted by Nutrafol.
