PETER THOMAS ROTH

Birchbox Breakdown

Peter Thomas Roth’s Mega-Rich Conditioner toes the line like a star, restoring even the most parched strands without a smidge of heaviness. You’ll have healthy, frizz-free hair in no time.

Sleek & Shiny

Just like the shampoo, this conditioner left my hair feeling sleek and shiny!!! It's very hard to find conditioner that moisturizes without leaving a greasy residue in my ultra fine hair, but this did the trick! So please with this item!!!

Very moisterizing

I was using some products that dried out my hair. I received a sample of this and it fixed up my hair even when paired with a drying shampoo. I bought a full size right away and have been happily using it ever since. I will very likely repurchase.

An unexpected favorite
Purchased

I actually initially tried this conditioner as a sample that was given in a hotel I recently stayed at, but loved it so much I ended up ordering it from Birchbox after I got so excited to find it available for purchase on this site! This product does what it promises, giving my hair shine and softness without weighing it down. I especially enjoyed this when my hair was much shorter and I was having a hard time adjusting to the new amount of shampoo and conditioner to use.

Leaves hair soft

I really enjoy this conditioner. It leaves my hair feeling soft but not too weighed down, which is important for my straight hair. Nice fragrance, not too strong.

Smells delicious
Purchased

I first started using this after it was in my hotel room on a trip. I LOVE the smell. It makes my hair look and feel good, too - definitely not weighed down or greasy.

Not a great product...
Purchased

I was really excited for this conditioner to arrive once I had ordered it! It sounded so promising - it would nourish and hydrate your hair, yet it was healthy too. What a let down - I tried to use it several times but each time I would rinse ti out it would leave my hair tangled in knots. It almost felt as though my hair was more tangled and less conditioned after I had used it - STRANGE. Perhaps it was just not the right conditioner for my hair...

Impressed

I used this at a recent hotel stay. I was impressed since it was better quality and actually conditioned more than your typical hotel toiletries.

Great find!

I came across this brand when I purchased a mascara and have since tried almost all of PTR products . This conditioner leaves your hair smelling great and feeling so smooth and soft. Try the shampoo !
