How to Use &honey Deep Moist Hair Oil: Viral Japanese Hair Care Explained

&honey Deep Moist Hair Oil has been going viral online and is also currently being promoted by K-pop idol Jeonghan from SEVENTEEN (!!!)

Just to be clear, it was already going viral before Jeonghan became the brand ambassador.

But does it really deliver smoother, shinier, more manageable hair, or is it just another viral beauty trend?

Before you decide to try it yourself, here’s a breakdown of what it is, its key ingredients, how to use it, and real-world impressions to help you decide if it’s actually worth it.

What is &honey Deep Moist Hair Oil

&honey Deep Moist Hair Oil is a Japanese finishing hair oil from ViCREA’s &honey Deep Moist line, used as the final step after &honey Deep Moist Shampoo and &honey Deep Moist Conditioner. This hair oil works best for people who want a quick improvement in softness, shine, and frizz control.

It is especially suitable for:

• Dry or frizzy hair that needs extra moisture and smoothing
  

• People who regularly blow-dry or heat-style their hair
  

• Hair that looks dull and needs a more polished, glossy finish
  

It may not be ideal for:

• Very fine or low-density hair, as it can feel heavy if over-applied
  

• People who prefer completely lightweight, oil-free styling products
  

In Japan, it’s popular because it gives an easy “salon hair” finish at home without breaking the bank. At around $20, it sits in the affordable drugstore range and has become a staple in everyday haircare routines.

Why It Works: Ingredients Explained 

This hair oil works by combining hydration, nourishment, and smoothing in one formula. I did some research to break down the key ingredients that make it effective:

Honey-based ingredients (honey, honey extract, hydrolyzed honey protein) - Honey is known as a humectant, meaning it helps attract and hold moisture in the hair. It is also mildly acidic, which can help the hair cuticle lie flatter for a smoother, more reflective finish. In addition, honey has natural antibacterial properties that may help support a healthier scalp. 

Argan oil - Commonly associated with reduced breakage and improved scalp and hair condition, which may help support healthier-looking hair over time. 

Ceramides (NG, NP, AP) - Ceramides are commonly described as key lipids that help support the skin’s natural barrier and help reduce moisture loss.

Silicones (Cyclopentasiloxane, Dimethicone) - Silicones are commonly used in haircare products to improve smoothness and frizz control. In some cases, they may accumulate on the hair depending on formulation type and cleansing routine.

Humectants (Glycerin, Hydroxypropyltrimonium Hyaluronate) - Humectants are commonly used in haircare to help attract moisture into the hair fiber, and are often paired with oils and smoothing agents to help maintain hydration and reduce moisture loss. 

Proteins (Keratin, Hydrolyzed Silk) - Help reinforce the hair fiber, temporarily fill in damaged areas of the cuticle, and improve smoothness and manageability, making hair feel stronger and easier to style.

In simple terms, it combines ingredients that 1. hydrate, 2. soften, 3. smooth, and 4. add a glossy finish to the hair. 

How to Use &honey Deep Moist Hair Oil (Step-by-Step) 

&honey hair oil is best used after shampooing on towel-dried hair, when the hair is still slightly damp. It can also be applied to dry hair for quick touch-ups to smooth frizz and refresh the ends. It works as a leave-in treatment and can be used after every wash or as part of a daily routine. 

Step 1: Start with a Small Amount in Your Hands

Dispense the oil into your palms and rub them together to distribute it evenly. Start with a small amount and build up only if needed, since too much can make the hair feel heavy. 

Step 2: Apply to Mid-Lengths and Ends

Apply it through the mid-lengths to the ends of your hair, avoiding the scalp. 

Step 3: Distribute Evenly Through Hair

Gently distribute it using your fingers or a wide-tooth comb for even coverage. 

Step 4: Style as Desired

Style your hair as usual, either by blow-drying for a sleek look or letting it air dry for a more natural result. As you can see in the picture, it gives the hair a more polished look.

FAQs 

Is &honey Deep Moist Hair Oil good?

It is most effective as a moisturizing and smoothing hair oil, but may feel too heavy or fragrant for some users. 

Can I use &honey hair oil every day?

Yes, it can be used daily, but only in small amounts. Overuse may lead to buildup or a heavier feel, especially for fine hair types.

Does &honey hair oil work on fine hair?  

Yes, but fine hair needs a very light application. Using too much can weigh the hair down, so it’s best to start with 1 pump or less depending on hair length.

Can I use &honey hair oil before heat styling?

 Yes, it can be used before blow-drying or heat styling. It helps reduce dryness and adds slip, making the hair easier to style, though it should still be used sparingly.

Is &honey hair oil a treatment or just a styling oil?

It works as both. It acts as a leave-in treatment to help improve moisture and softness, while also functioning as a styling oil that smooths frizz and adds shine. 

Is &honey Deep Moist Hair Oil Worth It? 

Yes! It quickly makes hair feel softer, shinier, and less frizzy. I can say that it does work well for daily styling and adding a healthy-looking shine to dry or dull hair. 

While results can vary depending on hair type and how much is used, most people find it works best as a small, buildable finishing step. Just be careful not to use too much, as with any hair oil, to avoid weighing the hair down. 

If you’re looking for an easy, affordable way to achieve softer, shinier, and more manageable hair, I can vouch that &honey Deep Moist Hair Oil is a great addition to your hair care routine!
