Treating hair that feels like straw requires intense rehydration and sealing in moisture to fix severe dryness, frizz, and brittleness. Key actions include switching to sulfate-free, hydrating shampoos, using weekly deep conditioning masks, applying leave-in conditioners daily, and avoiding heat styling. Trimming split ends and using protective oils also help restore texture.
Here are some lifestyle tweaks you can try.
You cannot fully rewrite genetics, but you can substantially improve hair thickness appearance and slow or partially reverse miniaturization using scalp care, nutrition, gentle styling, topical treatments (notably minoxidil), and selected procedures.
To moisturize extremely dry hair, focus on deep hydration with masks and oils, reduce washing and heat styling, use sulfate-free products, and lock in moisture with leave-ins, conditioners, and sealants like oils or butters, always applying products to damp hair to trap water and get regular trims for split ends.
Hair will slowly become drier, coarser, and thinner over the years. The truth is that as we grow older, the oils that our scalp relies on for nourishment decrease, resulting in drier, frizzier hair. Along with a change in oil production, our body stops creating melanocytes, the substance that colors our hair.
Not having enough vitamin C can make your hair dry and brittle. Vitamin C helps your body absorb iron, which is essential for growing healthy hair. The following factors can cause a lack of Vitamin C: Smoking.
The "Big 3" for thinning hair, especially male/female pattern baldness, are typically Minoxidil (Rogaine), Finasteride (Propecia), and sometimes Ketoconazole shampoo, or even Microneedling, forming a multimodal approach to stimulate growth and block hormones (DHT) causing hair loss, with Minoxidil boosting circulation, Finasteride inhibiting DHT, and Ketoconazole reducing inflammation and acting as a mild anti-androgen.
How to treat dry and frizzy hair
Keratin Treatment:
One of the most popular salon treatments for achieving silky hair is the keratin treatment. This intensive procedure involves infusing the hair with keratin—a protein that's naturally found in hair—to strengthen and smooth the hair shaft.
What hydrates hair the most? Products containing humectants like hyaluronic acid, glycerin, and aloe vera are highly effective at drawing and holding moisture in the hair. Deep conditioning treatments and leave-in serums with these ingredients tend to be the most hydrating.
With fine hair, you should avoid heavy, oil-based products, over-conditioning, excessive heat, and tight hairstyles to prevent it from being weighed down, greasy, or damaged; instead, opt for lightweight volumizing products, gentle washing, minimal heat, and loose styles, treating it delicately to prevent breakage and keep it looking full.
Hair Thickening Shampoos
Most experts recommend washing thinning hair 2-3 times per week to maintain optimal scalp health. This schedule allows your scalp's natural oils to nourish and protect your hair follicles while preventing excess buildup.
“You should be using a nourishing hair mask once a week if your hair is feeling straw-like due to lack of moisture,” Hurtado says. He recommends Briogeo's Don't Despair, Repair Deep Conditioning Hair Mask. “It helps repair damage and split ends while providing protein and moisture to strengthen hair.”
Signs of low porosity hair
The rarest hair type is generally considered Type 1A, which is extremely fine, straight, and wispy, lacking any natural bends or waves, making it difficult to hold a curl but naturally sleek and prone to oiliness. While curly hair types (Type 3 & 4) are less common globally, 1A stands out as the least voluminous and textured straight hair, often seen in people of East Asian descent, though it's considered rare across all populations due to its unique fineness.
The hair contains a medulla filled with plenty of dark pigment, which is thought to contribute to its shine and high moisture content. However, because East Asian hair is thicker and sometimes longer, it also tends to lose more moisture, which can lead to dryness and split ends.

Argan Oil
It is also high in antioxidants such as vitamin E, essential for both your scalp and hair. The properties of argan oil have been shown to assist with your hair's ability to maintain moisture by lubricating the hair shaft. We love argan oil for its ability to smooth hair and pump up shine!
How to hydrate dry hair: 9 simple tips
Coconut oil's unique ability to penetrate hair strands is known to help strengthen the hair cuticle. The oil is also an emollient, which means it leaves a protective layer on the hair that can help prevent water loss and may help protect tresses from damage.
Oily hair will require more frequent washing, while dry, damaged, wavy, or curly hair should go a few more days between washes. In terms of hair texture, tightly-coiled type 1 hair requires extra hydration and can go days or weeks between washes.
Key vitamin deficiencies linked to hair loss include Vitamin D, B12, Biotin (B7), and Iron, with low levels of these nutrients affecting hair follicle function, protein production (like keratin), and oxygen supply, leading to thinning or shedding; however, excessive intake of some vitamins (like A or selenium) can also cause hair loss, so a doctor should confirm deficiencies via blood tests before supplementing.
Japanese scalp treatments focus on cleansing, stimulating, and nourishing the scalp to create an ideal environment for healthy hair growth. These treatments remove buildup, improve circulation, and strengthen hair follicles, helping with early signs of hair loss and thinning.
