You’ve probably seen the videos. Someone is sitting in front of a ring light, vigorously massaging an expensive-looking oil or a DIY concoction into their scalp, claiming that if you just rub it in strands long enough, you’ll wake up with Rapunzel-level length by Tuesday. It looks therapeutic. It feels like it should work. But honestly? Most people are doing it completely wrong, or worse, they’re actually causing more breakage while trying to "infuse" their hair with nutrients that aren't even being absorbed.
Hair is dead. Well, the part you see is.
That’s the hard truth that most influencers ignore when they talk about "feeding" your hair from the outside. Once that strand leaves the follicle, it's essentially a fossilized tube of keratin. You can’t "nourish" it back to life like a houseplant. When we talk about the rub it in strands method, we have to distinguish between scalp health and hair shaft protection, because the two are worlds apart in terms of biology.
The Friction Problem Nobody Mentions
Most people think that the harder you rub, the better the product penetrates. Nope. Not even close. Your hair has an outer layer called the cuticle, which looks like shingles on a roof. When you aggressively rub oils or creams into the strands, you’re essentially ruffling those shingles. This creates friction. Friction leads to "hygral fatigue" or physical weathering.
Ever noticed those tiny white dots at the end of your hair? Those are fracture points. If you’re too rough when you rub it in strands, you’re literally snapping the internal bonds of the hair. You think you’re moisturizing, but you’re actually exfoliating your hair into oblivion. It’s a subtle disaster that takes months to notice until one day you realize your hair hasn't "grown" in a year. It's growing from the root; it's just breaking at the ends because of how you're handling it.
What the Scalp Actually Needs
The scalp is different. It's skin. It’s alive. This is where the rub it in strands philosophy actually has some scientific legs, provided you focus on the base and not the length.
When you massage the scalp, you're increasing localized blood flow. Studies, like the one published in Eplasty back in 2016, suggested that standardized scalp massages could increase hair thickness by stretching the cells of hair follicles. This mechanical stimulation tells the follicles to produce thicker hair. But notice the keyword: thickness, not necessarily speed.

- Use the pads of your fingers, never your nails.
- Move the skin, don't just slide your fingers over the hair.
- Keep it to about 4 or 5 minutes. Anything more is overkill and might trigger an overproduction of sebum, leaving you greasy.
Ingredients That Actually Sink In (and Those That Just Sit There)
Not all oils are created equal. If you're trying to rub it in strands using something like Jojoba oil, you’re wasting your time if you want internal repair. Jojoba is a sealer. It’s a wax ester that mimics human sebum. It’s great for shine and preventing water loss, but it doesn't "soak" into the hair. It sits on top like a raincoat.
If you want penetration, you need Coconut oil. It's one of the few oils with a molecular structure small enough to actually enter the hair shaft and bind to the proteins.
- Coconut Oil: High affinity for hair proteins, penetrates deep.
- Argan Oil: Mostly sits on the surface, great for UV protection and frizz.
- Castor Oil: Way too thick to penetrate the strand, but great for the scalp because of ricinoleic acid.
- Olive Oil: A middle-grounder. It can penetrate slightly but mostly acts as an emollient.
People get frustrated because they spend forty dollars on a "miracle" oil and then rub it in strands only to find their hair feels crunchy the next day. That's usually because the oil is just coating a dry strand, trapping the dryness inside while creating a barrier that prevents actual moisture (water!) from getting in.
The Porosity Factor: Why Your Friend’s Routine Fails You
You’ve heard of "high porosity" hair? It’s basically hair with holes in the shingles. If you have high porosity hair, you can rub it in strands all day and the hair will gulp it up, then let it all leak out five minutes later.
Low porosity hair is the opposite. The shingles are tightly shut. If you try to rub it in strands with a heavy butter or oil, it just pools on the surface. You’ll look like you haven't showered in a week, and your hair will still feel brittle. For these people, heat is the only way. You need a warm towel or a steamer to "open" the door so the product can actually enter. Without heat, the rubbing is just making a mess.
Dealing With the "Build-up" Cycle
Here is the irony: the more you rub it in strands, the more you have to wash your hair. The more you wash your hair, the more you strip away natural oils. This leads to a vicious cycle where you feel your hair is "dry," so you rub in more product, which requires a harsher sulfate shampoo to remove, which makes the hair even drier.

Honestly, most of us need to do less.
A lot of the "before and after" photos you see online aren't the result of a specific rubbing technique. They are the result of lighting, a fresh trim to remove dead ends, and perhaps a silicone-based serum that provides a temporary "band-aid" over the damage. There is no biological mechanism that allows a rubbed-in oil to "heal" a split end. Once it's split, it's over. Cut it off.
Real-World Application: The "Praying Hands" Method
Instead of a frantic rub it in strands motion, professional stylists usually recommend the "praying hands" technique. You take the product, rub it between your palms, and then sandwich your hair between your flat hands, sliding downward.
This smooths the cuticle down rather than ruffling it up. It’s a night and day difference for frizz control. If you're doing this on wet hair, be even more careful. Hair is at its weakest when it's saturated with water. The hydrogen bonds are temporarily broken, making the hair incredibly stretchy and prone to snapping. If you rub it in strands while your hair is soaking wet and you're being aggressive, you’re basically stretching a rubber band until it gets those "frayed" edges.
Misconceptions About Growth Serums
We need to talk about those "growth" serums that people rub it in strands near the roots. Most of them contain caffeine or peppermint oil. These do work to an extent by stimulating vasodilation. However, many "viral" brands include high amounts of alcohol to make the product dry faster.
If you're rubbing an alcohol-heavy serum into your strands repeatedly, you are essentially chemically parching your hair. Always check the ingredient list for "Alcohol Denat" or "Isopropyl Alcohol" near the top of the list. If it’s there, keep it away from your length. Only let it touch the scalp skin.

Actionable Steps for Better Hair Health
Forget the 20-minute intense rubbing sessions. They aren't helping. If you want to actually improve the quality of your hair, follow a logic-based approach rather than a "more is more" philosophy.
Stop the friction. When applying any leave-in or oil, stop the vigorous rubbing. Use the praying hands method or a wide-tooth comb to distribute product. Your cuticles will thank you.
Focus on the "living" part. If you’re going to spend time on a routine, spend it on your scalp. A 4-minute gentle massage with a light oil (like grapeseed or almond) can improve the environment where hair is born. This is the only way to impact the future of your hair.
Check your porosity. Drop a clean strand of hair into a glass of water. If it sinks immediately, you have high porosity and need proteins to fill the gaps. If it floats forever, you have low porosity and need heat/steam to get any product to work. Don't just rub it in strands blindly without knowing what your hair can actually handle.
Protect the ends. The ends are the oldest part of your hair. They might be three, four, or five years old. They don't need "rubbing"; they need a seal. Use a heavy occlusive (like a tiny bit of shea butter or a silicone serum) only on the last two inches to prevent them from drying out and splitting upward.
Wash with intention. Don't scrub your hair like you're washing a rug. Lather the scalp and let the suds rinse down the strands. This provides enough cleaning without the mechanical damage of rubbing.
By shifting the focus from "rubbing products in" to "protecting the structure," you stop fighting against the biology of your hair. It’s less about the effort you put into the rubbing and more about the intelligence of the application. High-quality hair care isn't about intensity; it's about consistency and friction management.
