Hair Growth at Home: 5+1 Tips for Fuller, Stronger-Looking Hair
From everyday hair care to scalp treatments, discover what can support healthy hair growth, what helps prevent breakage and where the evidence matters.
Noticing more hair in your brush, a thinner ponytail or ends that break before you reach your desired length? These changes can look similar, but they may have different causes.
Supporting hair growth at home starts with understanding what your hair needs. Adequate nutrition, gentle styling and consistent scalp care can all play a role. If you are experiencing increased shedding or visible thinning, identifying the cause is essential before choosing a treatment.
These five practical tips, plus one additional scalp care step, will help you build a more considered routine.
The Short Answer: What Helps Support Hair Growth at Home?
Adequate nutrition, gentle hair care and a consistent scalp care routine provide a useful foundation. Reducing breakage helps you retain length, while thinning hair may require treatment that addresses its underlying cause. The role of hair growth serums and scalp devices depends on the formula, technology and available evidence. Persistent or sudden hair loss should be assessed by a healthcare professional. [1]
1. Give Your Hair the Nutritional Support It Needs
What you eat matters alongside what you apply to your hair. Adequate protein and a balanced intake of vitamins and minerals help support normal hair function.
Which Vitamins and Minerals Matter for Hair?
-
Vitamin A: Supports normal skin function, including the scalp. Excessive intake can contribute to hair loss.
-
Biotin: Contributes to the maintenance of normal hair. Without a deficiency, taking more does not necessarily produce thicker or faster-growing hair.
-
Vitamin C: Supports normal collagen formation and helps the body absorb iron from plant-based foods.
-
Vitamin D: Low levels have been observed in several hair loss conditions. This does not mean supplementation improves hair growth in everyone.
-
Zinc: Contributes to the maintenance of normal hair, skin and nails.
-
Iron: Deficiency can be associated with hair loss. Supplementation should be guided by an identified need. [7, 8, 9]
What Should You Eat to Support Healthy Hair?
Build your diet around a variety of protein sources, vegetables, fruit and other nutrient-rich foods. Fish, eggs, beans, lentils, leafy greens and citrus fruit can all form part of a balanced diet.
If shedding persists, investigate whether a deficiency is present before adding several hair supplements to your routine.
Where Does Collagen Fit Into Your Routine?
If you want to support your skin as well as your hair, a collagen supplement containing additional vitamins and minerals may fit your routine.
DermaGene® REBORN NAD+ Collagen Longevity Beauty Drink contains hydrolysed marine collagen peptides, vitamin C, zinc and biotin.
Its zinc and biotin contribute to the maintenance of normal hair, while vitamin C supports normal collagen formation for the normal function of skin. These nutrient functions should be distinguished from claims about collagen alone.

2. Reduce Heat Damage to Help Retain Hair Length
Reducing hair breakage helps preserve the length you have already grown. This is particularly relevant if your hair appears to grow at the roots but never seems to get longer.
Choose a lower heat setting when blow-drying and keep the dryer moving. Use straighteners on dry hair at a low or medium temperature, and reduce how often you style with hot tools.
After washing, gently blot excess water with a towel instead of rubbing your hair vigorously. [2]
These habits help protect the hair shaft. They preserve length by reducing damage rather than directly increasing the rate of growth.
3. Keep Your Hairbrush and Scalp Devices Clean
A clean brush is a simple part of a consistent hair care routine. Remove trapped hair regularly and clean product residue using a method suitable for the brush material.
A conventional plastic comb and an electrical scalp device require different care. Always follow the manufacturer’s cleaning instructions for electrical equipment.
For microneedling tools, correct cleaning, disinfection and replacement of the treatment head are particularly important. Do not share your microneedling device with other people.
4. Choose Hairstyles That Do Not Pull on Your Roots
Repeatedly wearing tight ponytails, buns or braids can cause hair loss through prolonged tension on the hair follicles. This is known as traction alopecia. [4]
If your hairstyle pulls, hurts or leaves your scalp feeling tense, loosen it. Alternate your hairstyles and give your roots a break between tightly secured styles.
Pay particular attention if you notice thinning around your hairline or temples.
5. Understand the Evidence Behind Scalp Treatment Devices
Scalp devices use different technologies, and their evidence should be assessed separately. A study of one technology does not establish that every device using it will produce the same results.
Low-Level Light Therapy for Hair Loss
Low-level light therapy, often abbreviated to LLLT, has been studied for hereditary pattern hair loss, also called androgenetic alopecia. Clinical studies of specific devices have reported improvements in hair density with repeated use. [10]
The wavelength, light output, treatment schedule and device design all matter. Results from a studied laser or light device do not automatically apply to every LED comb.
DermaGene® Grow My Hair 3in1 combines radiofrequency, electrical stimulation and LED light in an at-home scalp device. If your routine currently focuses on shampoo, conditioner and hair masks, it offers a way to add a dedicated scalp treatment step.
However, these are distinct technologies with different evidence bases. Published light therapy research does not establish the effectiveness of its radiofrequency or electrical stimulation functions. Product-specific clinical testing would be needed to confirm the Grow My Hair device’s hair growth outcomes.

Microneedling for Thinning Hair
Microneedling creates small, controlled punctures in the skin, triggering a local repair response. It can also temporarily increase skin permeability.
Researchers have investigated microneedling as an additional treatment for hair loss, particularly alongside minoxidil. Some studies have reported improvements in hair count or thickness, but protocols vary and the quality of the evidence remains limited. [5]
DermaGene® MicroLuxe 4-in-1 offers a microneedling option for an at-home scalp care routine. An at-home device paired with a cosmetic serum should not be assumed to reproduce the outcomes of clinical treatment protocols.
Before starting scalp microneedling, discuss its suitability with a dermatologist, particularly if you are experiencing unexplained hair loss.
Follow the device instructions for treatment heads, frequency and compatible products. Do not treat broken, irritated or inflamed skin.

+1. Give Your Scalp Its Own Care Step
Conditioners and hair masks mainly care for the lengths of your hair. A scalp serum is applied directly to the scalp. They serve different purposes within your routine.
What Is in the DermaGene Hair Growth & Scalp Density Serum?
DermaGene® Hair Growth & Scalp Density Serum combines five featured ingredients:
-
1% Redensyl™
-
2.5% Capixyl™
-
0.5% GHK-Cu copper peptide
-
0.5% caffeine
-
0.5% Capilia Longa®
Its lightweight, leave-in formula is designed for regular scalp care without weighing down the hair.
How Should You Add a Scalp Serum to Your Routine?
Apply the serum directly to the scalp, following the product’s instructions for quantity and frequency. Parting your hair can help you reach the skin rather than coating the lengths.
If you use it with a scalp device, check both sets of instructions for compatibility and application timing. This is especially important with microneedling.

Frequently Asked Questions About Hair Growth at Home
What Can Help Support Hair Growth at Home?
Adequate nutrition, gentle styling and consistent scalp care provide a useful foundation. Reducing breakage helps retain length. If you are experiencing increased shedding or thinning, identifying the cause is important before choosing a treatment.
Why Is My Hair Not Getting Longer Even Though It Is Growing?
Breakage can offset growth at the roots, making your hair appear to stay the same length. Reducing heat exposure, brushing gently and conditioning the lengths can help preserve the hair you have grown. [2]
Does Biotin Stop Hair Loss?
Biotin is not a universal hair loss treatment. Supplementation may help when a deficiency is present, but taking extra biotin without a deficiency has not been established as a way to achieve fuller hair. [3, 7]
Is Collagen Powder a Hair Growth Treatment?
Collagen powder alone is not an established treatment for hair loss. A combined supplement may contain nutrients such as zinc and biotin that contribute to the maintenance of normal hair. Check the complete formula rather than attributing every benefit to collagen.
Do All LED Hair Combs Help Hair Grow?
No. Wavelength, output, exposure and treatment frequency matter. Clinical research evaluates particular devices and protocols, so its results cannot automatically be applied to every LED hair comb.
Can Microneedling Help With Thinning Hair?
There are promising findings for microneedling as an additional treatment, particularly for hereditary pattern hair loss. However, outcomes depend on the protocol and other treatments used. Evidence remains limited, and professional assessment is advisable before starting. [5]
How Long Does It Take to See Changes in Hair Growth?
Changes in hair growth and density generally require several months to assess. There is no single timeline that applies to every product, treatment or cause of hair loss. Less breakage and a change in scalp comfort are also different outcomes from new hair growth.
Can I Use a Scalp Serum With a Hair Treatment Device?
Yes, provided the product and device instructions allow it. With microneedling, check the serum’s suitability and application timing specifically. A product intended for routine application to intact skin is not automatically suitable for use immediately after needling.
Build a Scalp Care Routine That Fits Your Needs
If your routine has focused mainly on the lengths of your hair, consider whether your scalp needs its own care step.
