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.

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!!

Great!
Hair Type Wavy Hair
This conditioner makes my hair feel soft, hydrated, and noticeably stronger without weighing it down. The only downside is that the scent is a bit strong, but that wouldn't stop me from repurchasing. Complimentary from nutrafol
Love it
Hair Type Wavy Hair
The Nutrafol Strand Defender Conditioner is such a good pair with the shampoo it leaves my hair soft, smooth, and detangled without weighing it down. My ends feel hydrated but still light, and it gives that healthy, silky finish I love. Gifted by Nutrafol
Amazing

I have been watching the commercial on tv on this product line. This conditioner is great for my hair. The conditioner texture is very smooth and not watery. The product is made with quality ingredients and packaging. My hair is so smooth and shiny. This brand has great reputation and I trust them with helping my hair. Complimentary from nutrafol
No more tangled hair
Hair Type Wavy Hair
My hair was always hard to brush after wash and even throughout the day. This conditioner works like magic, my hair feels soft and protected. I have no problem brushing it, and especially during hair loss I don't want to pull my hair so much. This is definitely worth to try product! Complimentary from nutrafol

I really love this conditioner. . A little bit goes a long ways, and I can really feel my scalp being so squeaky clean. It removes so much buildup promoting my scalp to be healthy. It's not greasy and harsh . Gifted
