Nioxin System 4 Scalp & Hair Treatment offers accurate care for damaged, accelerated thinning hair by amplifying the diameter of strands, while also nourishing them. Fitted to one's needs, this third and final step towards healthier, fortified hair, hydrates strongly to fight advanced density loss. Under a cleansing, optimizing, and precise therapy, this product is ideal for color-treated hair with thinner, damaged roots. Thanks to the exclusive Scalp Access Delivery System 2.0 within it, the nourishing, non-aggressive, as well as soothing key elements, will reach every bit of your hair. Plus, this innovation forms a successful shield against UV rays, safeguarding strands from yet another peril.

Moreover, you'll attain full coverage due to the purifying yet deeply moisturizing properties of Hydrolyzed Keratin or Citric Acid. Denser, stronger hair is the perfect way to increase both your confidence and comfort as this professional treatment allows quick results to take place. In fact, it starts repairing strands from the first usage while also putting attention to detail at the forefront. As in all of Nioxin's ranges, it creates optimal results when combined with a cleansing shampoo and smoothing conditioner. Besides, the feather-like finish and cooling sensation are not only addictive but evidently calming. Indeed, fuller-looking hair with a refined shape must come from a flawless, relaxed scalp for an ideal regeneration.

Features:

  • Texture: cream;
  • Hair issues: progressive hair loss, color-treated hair;
  • Time of application: daily, during the morning or evening;
  • Age: 20+;
  • Hair type: all hair types, including sensitive scalps;
  • Main benefits: revitalizes the hair from the inside out, boosts radiance, improves the shape, volume and density, nourishes the roots of hair strands, soothes and hydrates, shields from free radicals and other urban threats, offers a feather-like finish, preserves hair color treatments, improves overall texture, clinically approved.

Main Ingredients:

  • The trademark Scalp Access Delivery System 2.0 specifically helps thicken weaker hair, working from the surface of the head to distribute favorable properties evenly. In addition, it features a potent complex of components meant to protect strands from harmful UV rays;
  • Citric Acid is 100% natural and tends to be used as a pH regulator. Besides, when in moderation, it makes your hair increasingly soft, smooth, and radiant. Plus, it adds thickness, volume, as well as layers of protection combined with a healthy dose of nutrients;
  • Polysorbate 80 is an excellent purifier and emulsifier, eliminating DHT, a hormone that causes hair loss. Plus, one way it supports hair growth or regeneration is by triggering histamine release in the scalp, stimulating cell renewal;
  • Lastly, Hydrolyzed Keratin will soften your hair noticeably. Besides, other qualities include minimizing breakage, flaking, and frizz, as well as stimulating elasticity, shine, and moisturizing intensely. This large protein molecule is broken down so it can penetrate the hair cuticle and balance drier scalps.

How to Use:
Apply Nioxin System 4 Scalp & Hair Treatment directly on all the areas of your scalp. Pay special attention when distributing the cream and perform a delicate massage with your fingers. Don't forget to incorporate the product into your hair strands as well. Let it rest for about a minute and then rinse abundantly with warm water. For maximum results, use on a daily basis as the final step of Nioxin's System 4. Apply, Nioxin System 4 Cleanser Shampoo and Nioxin System 4 Scalp Therapy Conditioner beforehand for improved care.

No sunburn
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
We have been using this in Hawaii for the past week (it meets Hawaiian sunscreen requirements). Out of the 4 of us, none of us have gotten a sunburn at the beach or pool! We do reapply every 1 to 2 hours. Will buy again!

Light, Moisturizing, and Smells Great, Totally Worth It
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
I’ve been loving this Neutrogena Beach Defense sunscreen. It goes on so smoothly and feels more like a light body lotion than a typical sunscreen, which I really appreciate. It’s super easy to apply and doesn’t leave that sticky or greasy feeling that a lot of other sunscreens do. My skin actually feels hydrated after I use it, which is a nice bonus especially when I’m out in the sun all day. The scent is fresh and beachy, not overpowering or too “sunscreen-y,” and it fades nicely after a while. It also absorbs quickly and doesn’t leave a white cast, which makes it great for reapplying throughout the day. I’ve used it at the pool, the beach, and just for everyday sun protection, and it’s held up really well every time. It’s a little pricier than some drugstore sunscreens, but honestly, the quality makes it worth it. It feels good on my skin, protects well, and doesn’t make me feel gross after hours in the sun. I’ll definitely be picking up another bottle when this one runs out.

Protected Our Skin and Smells Good
Size: 6 Ounce (Pack of 1)
I love this stuff! My husband and I bought it as a last minute grab for our honeymoon and it was well worth it! I'm very sensitive to the sun AND to sunscreens, so I needed something with simple ingredients that would also protect my skin without breaking me out. This not only kept away the burning rash I get from the sun, but protected my husband and I from any sunburn at all. It worked not only in dry conditions, but it stayed on for hours after we swam in the ocean. We also liked the fact that it smelled herbal, almost like pizza/Italian seasoning. That didn't bother us because we both hate the smell of most sunscreens. If you have sensitive skin or are looking for a more natural product, I highly recommend this!

Great reef-safe, easy-to-apply sunscreen (comparison of three ThinkSport products)
Size: 6 Ounce (Pack of 1)
I will start by saying that I am used to traditional non-mineral sunscreens and tend to only buy physical/mineral-based sunscreens when I'm going to be in a tropical ocean and need something reef-safe, though more and more kids sunscreens are shifting to mineral-based. After quite a bit of research I settled on ThinkSport for my family's recent trip to Hawaii, and I'm very pleased with it. I brought and used three types of Thinksport sunscreen: Thinksport Kids lotion (yellow/orange and teal squeeze bottle), Thinksport adult lotion (Black, white, and orange squeeze bottle), and Thinksport adult spray (black, white and orange spray bottle). All protected us from sunburn and rubbed in to be invisible as long as skin was dry and free of visible hair (visible whiteness persisted around my husbands facial stubble and chest hair). The only difference between the kids lotion versus the adult lotion is scent--the kids version has a fruitier, more tropical but not-too-strong scent (possibly coconut and something else? it was hard to identify) that I found unobjectionable (though one if my kids wasn't a fan), and the adult lotion had a lighter, less sweet, more citrus-y scent (my son though maybe lime and mint, but I'm not sure that's accurate) that I LOVE. The adult spray had no discernible scent, so I suspect the kids spray might be fairly unscented as well. The easiest to apply by far was the spray--it sprays on white, but feels very light, rubs in easily, and becomes invisible quickly. I was a little worried about whether it could possibly be effective given how light and thin it felt, but it was! The lotions weren't thick for a lotion (but much thicker than the spray) and went on easily, but took more rubbing in to disappear than the spray (this is consistent with my experience with lotion vs spray in traditional sunscreens as well). Invisibility was harder to get after a second or third application or when skin was damp, but all-in-all I found all three Thinksport products to be superior to other mineral-based sunscreens I have tried in the past. In the future I'll probably buy the adult thinksport spray for my kids and husband (who all much prefer a spray-on sunscreen) and the adult thinksport lotion for myself (because I love the scent and don't mind rubbing it in).

Dependable sun protection for active days outdoors
Size: 6 Ounce (Pack of 1)
I like how this sunscreen provides reliable broad-spectrum protection and holds up well during outdoor activities. The zinc oxide formula gives me peace of mind, and I appreciate that it's water resistant and reef-safe. It applies smoothly for a mineral sunscreen and stays on effectively during sports, swimming, and long days in the sun. Overall, it's a trustworthy option for anyone looking for strong sun protection.
