Varied results
I have fine (and thinning) hair so it's nice to have a formula specifically for this need. The scent is fresh, clean, and citrusy without being overbearing. I did notice it doesn't suds up/lather very nicely so it's doesn't feel like it's doing a good job as you apply to scalp and hair in shower but...

Highly recommend trying this product
Hair Type Very Curly Hair
This product was amazing I absolutely loved trying this product. It left my hair and scalp feeling so clean and sooo soft. It made my hair feel and look stunning. Hardly no frizz at all. Received as part of an educational promotion.

Best for my damaged hair
Hair Type Wavy Hair
I've been using the Oplay No.4 shampoo for a while now, and I can really see the difference in my hair. I have balayage highlights, and my ends were starting to feel dry and a little deteriorated from the lightening. These two product have helped bring my hair back to life. The shampoo gives a nice clean without stripping or making my hair feel squeaky, and the conditioner is rich but never heavy. After each wash my hair feels soft and smooth, and the shine is amazing—it actually looks healthier and more hydrated. The light scent is fresh and not too strong, which I love.

This maintence and volume shampoo is like magic. My hair was so dehydrated and frizzy that nothing was working. I decided to try this and I will say I am so impressed. Just after a few times of washing my hair with this shampoo I have seen a drastic change for the good. I feel I will not be using another brand any more. This by far is now my favorite shampoo.
I would get this product again and again!
Hair Type Straight Hair
This product made my hair feel so soft! I have very dry and fine straight hair and this product has given me so much shine and volume! It really worked wonders for my hair considering it falls out a lot too! I got this product free in exchange for my honest review.

Great lather
Hair Type Wavy Hair
Overall my hair feels softer, smoother, and more manageable after using this shampoo. The shampoo left a nice shine that lasted throughout the week. The biggest improvement is that my hair looks healthier. The scent is fresh, clean and lingered throughout the day. The smell is somewhat subtle, but it's definitely noticeable. I did find the shampoo foamed easily and suds up well. A little bit of product goes a long ways. I used a quarter size amount each time and washed my hair twice. I have a lot of fine hair that is comparable to cotton candy and it is dry. This shampoo added moisturizer without weighing my hair down. It did not leave it greasy. There is no sticky, tacky residue left behind. I do recommend this product and feel satisfied with it. My suggestion would be for Olaplex to change the packaging as it is too stiff to get the product out well. Also, it's white and I prefer the frosted clear they have used for some other products. I do recommend this product and will continue to use it. This product was given to me for free in the exchange for my honest review.
