    Best remedy for over processed hair!

  2. Rated 5 out of 5


    My absolute FAVORITE N4 product by far. It smells amazing and makes my hair incredibly soft. Love. You will not be disappointed.

  3. Rated 5 out of 5


    I received a sample of this in my Birchbox and it was amazing! It smelled nice and left my hair so soft and silky and overall healthier looking and feeling. The application process was simple and didn’t take forever which is a huge plus especially when time is of the essence.

    I was worried about using this product on my color treated hair but it was perfect. It cleaned all of the product from my hair and left my hair shiny and soft. I was very pleased with this product.

  5. Rated 5 out of 5


    Ultimately i didnt recieve this in a birchbox, but rather upon request along with a bundle of other samples from this company!
    First of all, the smell was extravagant and the way it left my hair feeling was magical 🙂
    I even left it on longer than the reccomended time.
    After my hair dryed i could instantly tell a difference.
    So would i reccomend this product?!
    You bet your butt i would!
    10 stars, all the way!

    Such a great product- really nourishes my fine hair without weighing it down. Like all No. 4 products, it smells like HEAVEN!

    Left my hair silky smooth and very moisturized! The smell is amazing too! I have fine hair and it didn’t weigh my hair down at all.

  8. Rated 5 out of 5


    This product is pure perfection! I have very dry, curly hair and I live in Southern California, so this masque does a great job at moisturizing my hair without it feeling too heavy or greasy. Once dry, I notice less frizz and a softer feel which makes styling (or even air drying) much easier. Bonus: it smells good! My only complaint is that the sample I received wasn’t a full size version. 😉

    I can’t even explain how excited I am that these samples came in my Birchbox! Love, Love, Love. My hair has never looked so good in humid weather!

  10. Rated 5 out of 5


    This might be the best masque I’ve ever used on my hair. The N.4 products are a favorite of mine, and this left my color treated hair feeling like silk. Like all the products I have tried from this brand, it smells incredible as well.

  11. Rated 5 out of 5


    I’m constantly dying my hair but this masque rescue my hair completly. I used this with the clarifiying shampoo my hair is so soft, shiny and more manageable I highly recommend it to anyone who wants beautiful hair.

    Makes my hair feel healthy and strong I almost always use it especially in the summer. The sun dries out my scalp and hair and this helps bounce my hair back to normal!

    This reconstructing masque is amazing. It always leaves my hair feeling stronger and silky smooth. The other thing I LOVE about this product, is the fact it does not weigh my hair down like most conditioning treatments. I give his product an A++++

    I received a sample of this product in my birchbox and I fell in love it makes my hair look and feel amazing and it smells wonderful!! I have recommended this product to family and friends.

  15. Rated 5 out of 5


    The best thing about this is the fact it tames frizzy hair good- very good! My hair is naturally curly and tends to be dry most of the time if I don`t put a moisturizer in or a styling product. After I shampooed and applied this in, I massaged it into my scalp and smoothed it throughout my hair. As I was massaging the liquid which then lathered richly on my hair, my scalp felt cooled down. It felt refreshing on my scalp and smoothed gently throughout my hair. I left it in my hair for about 20 minutes. Indeed, even after I washed out the treatment, my scalp still felt cooled and revived. Some parts of my hair are regularly dry, and look shriveled down. After I washed out the treatment that was on my scalp and smoothed out all through my hair, they looked more full and bouncier. My twists are regularly fragile and not delicate. This masque made them smoothed out and inconceivably soft. After I brushed out my hair, I saw that my twists looked fairly more and thicker and I owe that to this treatment for the way that it recuperated my curls and in light of the fact that now I have less breakage. And with less breakage, more hair is on my scalp so I can do a lot of styles with it! I now have less hair strands in my brush on account of this masque and the Support Solution likewise from Number 4. I additionally saw that after I washed out the treatment and even following a couple of days, my hair stayed curly and the finishes still look more full and not dead like they used to. All things considered, this masque is awesome to treatment your hair in every 3 days to keep up your hair and keep it solid!

    I received a sample of this product and I gave it a try. I was astonished. My hair hasn’t been this curly, light, amazingly soft and bouncy in ages! Especially the part that has color in it. I am in love and I will be buying a bottle because I saw results on my very first application. Now, I think I can’t live without it.
